This Matlab code transmits the recorded audio signal and transmits it over the additive white Gaussian channel (AWGN) using QPSK modulation. Receiving side using a low pass filter to cancel the noise to recover the signal. The recorded, transmitted and recovered signals are plotted in time and frequency domain. This code also calculated the power spectral density of the recovered signal.
