Discuss the performance differences in choosing short and long timers/timeouts as a designer for the data-link layer simplex stop-and-wait for noisy channel protocol?

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…

Problem Five Consider a serial port operating with a baud rate of 10,000 bits per second. Draw the waveform occurring at the UOTX output (voltage levels are +3.3 and 0) when the ASCII 'a' (0x61) is transmitted on UARTO. The protocol is I start, 8 data and 1 stop bit. UARTO is initially idle, and the software writes the Ox61 to UARTO DR R at time=0. Show the UOTx line before and after the frame, assuming the channel is idle before and after the frame.

The difference between an isochronous and synchronous connection may be described by comparing and contrasting these two kinds of connections.
