Problem 4 The pulses received in a binary digital communication system are given below, where Tb = 5 ms. p(t) 1V q(t) Tb Tb/4 Tb -1V- Tb/2 -A Tb/2 (a) Set the value of the constant A so that pulses p(t) and q(t) have the same energy. (b) Specify the block diagram of the matched-filter-based optimum receiver (based on the realization by correlator). The specification includes the correlator pulse and the threshold value. (c) If noise is additive, white and Gaussian with Sn(f)=N/2 = 0.5 mW/Hz, find the error probability that this receiver would yield.
