2. (20 points) Simulate the effect of multipath in wireless communication. Generate dumped sine wave x(t) with amplitude A-1 and frequency f=400Hz sampled at F= 11,025Hz with time constant 1 second (i.e. e). Assume that the signal is transmitted over three paths, so that the received signal is y(t) x(t) +0.4x(1-0.2) + 0.2x(-0.4) Determine the number of samples corresponding to delay using sampling frequency Fs from the file. Plot the function x(t) and output y(t) and use sound function in Matlab to listen to original and received signals. 2. (20 points) Simulate the effect of multipath in wireless communication.
