2.2 - Multiple Access - FDMA/TDMA/CDMA/OFDMA - Fundamentals of 4G (LTE)
 
06:08
Multiplexing is the process of combining multiple signals and transmitting them over a common channel and it is implemented on telecommunication using Multiple Access as a Application. Here, Multiple Access is explained with the example of Wi-Fi Hotspot sharing its internet connection among multiple users by providing them a frequency block over which they can transmit and receive data. The greater the size of this block, greater is the throughput. There are several way by which we can use Multiple Access Technique such as TDMA, FDMA, CDMA, W-CDMA, SDMA, OFDMA, SCMA. We have also mentioned, How TDMA and FDMA, CDMA, W-CDMA works and implemented in Earlier Generation system which is AMPS, GSM, GPRS, EDGE, UMTS, HSPA+. To overcome issues faced in earlier generation such as, - Low Throughput - Low Spectral efficiency - Resource wastage and many more, We have introduce next Generation Multiple Access technique which is already deployed in WIFI and in WIMAX, but due to lack of backward compatibility and support for Mobile communication in WiMAX, Operator started to working OFDM to include in LTE.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In telecommunications, a digital multiplex hierarchy is a hierarchy consisting of an ordered repetition of tandem digital multiplexers that produce signals of successively higher data rates at each level of the hierarchy. Digital multiplexing hierarchies may be implemented in many different configurations depending on; (a) the number of channels desired, (b) the signaling system to be used, and (c) the bit rate allowed by the communications media. Some currently available digital multiplexers have been designated as Dl-, DS-, or M-series, all of which operate at T-carrier rates. In the design of digital multiplex hierarchies, care must be exercised to ensure interoperability of the multiplexers used in the hierarchy.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share an expensive resource. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel, such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX or DMX). Inverse multiplexing (IMUX) has the opposite aim as multiplexing, namely to break one data stream into several streams, transfer them simultaneously over several communication channels, and recreate the original data stream.

Advantages and Disadvantages of Digital Communication System [HD]
 
12:44
Here you will know, why digital communication is preferred to analog communication. We will also discuss Disadvantages along with advantages of digital communication. For more detailed description, visit my blog (link below) http://www.engineeringmadeeasypro.com/ We know, that the electronic communication can either be analog or digital. Today’s world is going digital, so it is really important to understand, the advantages of digital communication, that are responsible for the digitalization everywhere. So here in this post, we will see, why digital communication is preferred over analog communication? But there are also some disadvantages associated with the digital communication. These disadvantages will also be discussed here. So first let's start with the advantages of digital communication. Advantages of digital communication # Digital communication systems are simpler and cheaper in implementation as compared to analog communication systems. It has become possible due to advancements in Integrated Circuits (IC) technology. These ICs are very small in size, reliable and cost-effective. Such ICs are used in digital communication, # In digital communication, it is possible to use multiplexing to merge speech, video and other forms of data for transmission over a common channel. The multiplexing is of various types like Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM) or Code Division Multiplexing (CDM). I don’t want to deviate from the current topic, so I will discuss the multiplexing in separate post. # High level of privacy can be obtained in digital communication using data encryption technique. This privacy provides the facility to allow the transmitted signals, to be received only by the permitted receivers. This feature is of great importance in military applications. # In digital communication channel encoding is used. Because of this encoding, there is less accumulation of noise from repeater to repeater, in case of long-distance communication. Apart from this, the digital signals tend to be less affected by noise as compared to analog signals. # It is possible to perform lots of operations on digital signals, like Digital Signal Processing (DSP), data compression, image processing etc. # It is easy to detect and correct errors in digital communication. This easy detection and correction of errors is possible due to the use of channel coding in digital communication. So these were the advantages of using digital communication. These benefits encourage the use of digital communication in place of analog communication. Now we will discuss some disadvantages that are associated with the digital communication. Disadvantages of digital communication # More transmission bandwidth is required in digital communication as compared to analog communication. This is due to the increase in the data rate when analog signal is converted into digital signal. # In digital communication, in case of synchronous modulation, synchronization is required. # Due to various stages used in conversion, high power consumption is another drawback of digital communication. # Sampling error is introduced in the sampling of signal. # Circuits that are used in digital communication are comparatively more complex and sophisticated. So this was the discussion about both advantages and disadvantages of digital communication but it’s worth mentioning that the advantages of using digital communication are more in comparison to disadvantages. Therefore digital communication is replacing analog communication nowadays. This video is created by Lalit Vashishtha, Founder and owner of 'Engineering Made Easy, YouTube Channel.

Opening package from Aliexpress (16-Channel Analog/Digital Multiplexer) + Test
 
04:40
Opening package from Aliexpress (16-Channel Analog/Digital Multiplexer) on base CD74HC4067 (Texas Instruments) http://got.by/2mj5i - Link on Aliexpress Description CD74HC4067: This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can’t be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins! Since the mux/demux also works with digital signals, you can use it to pipe TTL-level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select any one of those 16 devices to listen to. If you want two-way communications, you can add a second board to route your microcontroller’s TX line to 16 device’s RX lines. By using multiple boards, you can create similar arrangements for I2C, SPI, etc. The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching.

ASK FSK PSK Modulation/Digital Modulation Techniques/Amplitude, Frequency and Phase Shift Keying
 
13:13
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ This Video discusses Digital Modulation Techniques (ASK, FSK and PSK). The Waveforms, Definition and Basic Concepts of each digital modulation Techniques are discussed here. This Video also explains the basic difference between digital modulation and analog modulation. The digital modulation techniques are amplitude shift keying (ASK), frequency shift keying (FSK) and Phase shift keying (PSK). First of all let's understand, what is modulation? Modulation is a process, where some characteristic of the carrier wave (amplitude, frequency or phase) is varied in accordance with the instantaneous value of the modulating (message or baseband) signal. So if amplitude of the carrier wave is varied, then it is called as amplitude modulation, but if frequency or phase of the carrier wave is varied, according to the instantaneous value of the modulating signal, then it is known as frequency modulation or phase modulation respectively. So now let's Understand the basic difference between continuous wave modulation and digital modulation- Difference between Continuous Wave Modulation and Digital Modulation- Amplitude Modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM) are the examples of Continuous Wave (CW) modulation, while Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK) and Phase Shift Keying (PSK) are examples of Digital Modulation Techniques. The basic difference between continuous wave Modulation and digital modulation techniques is based on the nature of message signal (modulating signal). In continuous wave modulation, the message signal is of analog nature but in digital modulation, the message signal is of digital nature (Binary or M-ary encoded version). In both of these modulation techniques, the carrier wave is of analog form. Here it is interesting to note that, the three forms of digital modulation techniques that is ASK, FSK and PSK are analogous to AM, FM and PM of continuous wave modulation respectively. So now let's discuss each digital modulation technique (ASK, FSK and PSK) in detail- Amplitude shift keying (ASK) In ASK, the amplitude of the carrier wave is changed (switched) according to the digital input signal (modulating signal). Therefore amplitude shift keying is analogous to Amplitude Modulation (analog modulation). ASK is analogous to AM, because in Amplitude Modulation (AM), amplitude of the carrier wave is changed according to the instantaneous value of the modulating (message) signal, in the same way in ASK also, the amplitude of the carrier wave is switched (varied) according to the instantaneous value of the modulating signal (digital input signal). The difference is only of the nature of the modulating signal. In amplitude modulation, the modulating signal is of analog kind but in digital modulation, it is a stream of digital bits. the amplitude of the sinusoidal carrier wave is switched, as per the digital input signal. The carrier wave is either not transmitted or transmitted for digital input signal '0' or '1' respectively. That is why amplitude shift keying (ASK) is also called as "ON - OFF Keying (OOK)". Now we will discuss the Frequency Shift Keying (FSK) Frequency Shift Keying (FSK) If the frequency of sinusoidal carrier wave is varied (switched) as per the digital input signal, then it is known as the frequency shift keying (FSK). It is analogous to frequency modulation (analog modulation). The reason behind why FSK is analogous to FM, is.... In Frequency Modulation (FM), the frequency of the carrier wave is varied according to the instantaneous value of the modulating signal, in the same way in frequency shift keying also, the frequency of the sinusoidal carrier wave is varied (switched) as per the digital input signal. The difference is only of the nature of the modulating signal. In FM the modulating signal is of analogue nature while in FSK modulating signal is digital. So here the basic purpose of Frequency Shift Keying (FSK), is to modulate (change/switch) the frequency of the carrier wave, according to the digital input signal. So in Frequency Shift Keying (FSK), we have two types of frequencies of the carrier wave, low frequency for the transmission of '0' and high frequency for the transmission of '1'. In this way, in Frequency Shift Keying (FSK), the information of the digital input signal is present in the frequency variations of the carrier wave. That is why it is known as frequency shift keying. Now let's discuss the Phase Shift Keying (PSK) Phase Shift Keying (PSK) In phase shift keying, phase of the carrier wave (analog) is varied as per the digital input signal. Phase shift keying is analogous to Phase Modulation (analogue phase modulation). The phase shift keying is very much similar to Phase Modulation (PM), because in both of these modulation techniques

Quadrature Amplitude Modulation (QAM)/QAM Modulation/QAM Transmitter and Receiver/Block Diagram [HD]
 
10:19
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ This video is about Quadrature Amplitude Modulation (QAM). Quadrature Amplitude Modulation (QAM) Transmitter and Receiver have been discussed here. You will get here the basic concept of QAM modulation and why it is called as Quadrature Amplitude Modulation. Block Diagrams of QAM transmitter and Receivers are also explained here. Quadrature Amplitude Modulation (QAM) is also called as bandwidth conservation scheme. In Quadrature Amplitude Modulation two carries are used in quadrature (phase shift of 90 degrees). QAM is a combination of AM and PM in analog case and ASK and PSK in digital case. Introduction of Quadrature Amplitude Modulation (QAM) Quadrature Amplitude Modulation (QAM) can be used, either with analog signals or digital signals. If the message signal is analog in nature, then we use it with Amplitude Modulation (AM) but when the message signal is in digital form, then Amplitude Shift Keying (ASK) is used. Using QAM, it is possible to transmit two analog message signals or two digital bit sequences by modulating carrier wave's amplitude using analog modulation technique (AM) or digital modulation technique. This modulation scheme is also known as 'Quadrature Carrier Multiplexing'. Now we will understand, what is the meaning of 'Quadrature' in Quadrature Amplitude Modulation (QAM). Actually in quadrature amplitude modulation, the two carrier waves are used, that are out of phase by 90 degrees. Therefore this scheme is known as quadrature amplitude modulation, and these carriers are known as Quadrature Carriers. These modulated waves are summed at the output of the transmitter, therefore the final waveform is the combination of both PSK and ASK in digital case or PM and AM for analogue case. Now we will understand this concept with the help of block diagrams of QAM Transmitter and QAM receiver. In this image, you can see that here we are transmitting two message signals of analog nature x1(t) and x2(t). Observe that it contains two product modulators. The inputs to the first product modulator is, message signal x1(t) and the carrier wave, while the inputs to the second product modulator are analogue message signal x2(t) and the carrier wave with a phase shift of 90 degrees. Here we have used a 90 degree phase shifter for phase shifting. Mathematical Representation of Multiplexed Signal s(t) Because we know, when the product modulator is supplied with a message signal and the carrier wave, then we get amplitude modulated wave in the output. So you can observe here that, quadrature amplitude modulation (QAM) is the combination of both Amplitude Modulation and phase modulation (As phase change of carrier wave takes place here). This was the case for analog modulation, but if we talk about QAM with digital modulation, then, at the place of analog message signal, we use digital messages. In this case it would be a combination of Amplitude Shift Keying (ASK) and Phase Shift Keying (PSK). Now see the Output of the QAM transmitter. Here the outputs of two product modulators are added and the resultant output is the multiplexed signal S(t). So this QAM scheme enables two modulated signals to occupy the same transmission channel and allows the separation of these two message signals at the receiver output therefore it is also known as 'Bandwidth Conservation Scheme'. With this scheme we are simultaneously transmitting two amplitude modulated waves (in case of analog modulation) or two amplitude shift keying signals (in case of digital modulation). Therefore this allows us to use the same transmission channel. And at the receiving end we can easily detect these message signals. Now it's time to discuss the block diagram of QAM receiver. As you can see here, block diagram contains 5 components... Two product modulators, one 90 degree phase shifter, and two low pass filters. Multiplexed signal S(t), which is output of the QAM transmitter, acts as the input to the QAM receiver. This multiplexed signal is applied to the inputs of both the product modulators. For the First product modulator therefore two inputs are- Multiplexed signal s(t) and the carrier wave while the inputs to the second product modulator are- multiplexed signal s(t) and the carrier wave with 90 degree phase shift. Now the outputs of these product modulators are passed through the Low Pass Filters (LPF) as depicted in the image. So at the outputs of these are low pass filters, we get the message signals. The oscillators used to produce carrier waves at the transmitting and receiving ends must be in coherence i.e. the carriers at the transmitting and receiving ends must be in same phase. In this way we get back the modulating signals x1(t) and x2(t)(message signals) at the receiving end. For more details you can visit my BLOG- http://www.engineeringmadeeasypro.com/
