3.[%20] Consider a digitally modulated signal with pulse shaping p(t)=sinc(Ft), where sinc(x)= . The transmitted waveform is a,p(t), and symbol a, belongs to a BPSK constellation with intersymbol spacing d. The noise at the receiver is additive white Gaussian with autocorrelation. At the receiver, the signal is passed through the optimal filter followed by sampling at T. What is the resulting probability of error? 4. [20] Consider a digitally modulated signal with pulse shaping filter where is the unit step function. The transmitted waveform is a p(t), and symbol a, belongs to an ASK constellation with intersymbol spacing d. The noise at the receiver is additive white Gaussian with autocorrelation. At the receiver, the signal is passed through the optimal filter followed by sampling at T. What is the resulting probability of error? 5.
