5. [%20] Consider a digitally modulated signal with pulse shaping filter p(t) = Ke-t²u(t), where u(t) is the unit step function. The transmitted waveform is aop(t), and symbol ao belongs to a ASK constellation with intersymbol spacing d. The noise at the receiver is additive white Gaussian with autocorrelation 8(t). At the receiver, the signal is passed through the optimal filter followed by sampling at T. What is the value of K such that the pulse has unit energy? 2
