You will need to write a script to plot the approx- imated expressions and the simulation results in the same graph. Upon completion, a plot shows waveforms associated with the transmission of ten random bits over an AWGN channel, with a rectangular pulse shape and an integrate- and-dump receiver. Based on the scaling property, discuss the results. Determine the excess bandwidth and sketch carefully the spectrum, paying particular attention to the frequency values. This serves to increase the reliability of the received data and improves the quality of the received signal. No integrals required. Discuss how this can be used to enhance performance.
