In a baseband communication system, s₁ (t): Sin (²7), 0≤t≤T/2 = {A. Sin (² and S₂ (t) = S₁ (t- 0, Else T/2) are transmitted for the bits "1" and "0", respectively. Find the bit error rate (BER) expression of this system over additive white Gaussian channel (AWGN) for P(1)=1/3, P(0)=2/3 and plot it. Do the simulation of the system to obtain BER curve versus SNR. Compare and comment on the theoretical and simulated BER curves.
