Consider a digital multimedia transmission system. Separate audio and video coders are used to encode these signals. Audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 2,000 bytes long, which includes a 48-byte header. The system generates one packet every 40 ms. Calculate the following values: a. The minimum data transmission rate required to support the above system. b. The minimum signal-to-noise ratio (SNR) in dB required to transmit the above audio and video information. Assume a 400-kHz transmission channel bandwidth is used. c. The end-to-end packet delay over a 50-km link, using answer in Part a).

The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent. The equations of the carrier signal, the original signal to send, and the modulated signal combining the two signals are respectively: VI-V sin (2nfet) V2=Vm sin (2πfmt) V3-V sin (2nfet)+V sin (2nft)* sin (2nft) Supposing that V-Vm-1, fc-20, fm 1. Write a MATLAB program that plots the three signals with single call, the graphs must be contain (desired title, axis labels, annotations, with symbols for color, style, and marker) for each graph. Use the step 0.0025 for the time.
Your challenge is to use MATLAB to plot a received signal at a base station in a multipath channel when the transmitter sends a sinusoidal carrier signal. A transmitter sends a sinusoidal signal of frequency 1.5 MHz to the base station. There is a line-of-sight (LoS) path to the base station receiver, with delay 1 usec. The signal on this path is attenuated in amplitude by a factor 0.9 (the LoS amplitude gain). There are also three single bounce paths, one of delay 2 usec, with an amplitude gain of 0.5, one of delay 7 usec, with an amplitude gain of 0.4, and a third of delay 10 usec, with amplitude gain of 0.2. These parameters are fixed and do not change during the transmission. The project is to write MATLAB code to obtain the signal received at the receiver. Plot the signal over a time interval of 20 usec, including axes, and provide units for the time axis. Then answer the following questions: a) How is the output signal frequency related to the input signal frequency? b) Does the…
