Question

Input signal Output signal FIGURE P4.4 Probability of Error Calculatiorn 4.5 The formula for the optimum threshold in the receiver of Figure 4.4 is, in general, given by Equation (4.37). Discuss, in graphical terms, how this optimum choice affects the APTER 4BASEBAND PULSE TRANSMISSION contributions of the two terms in Equation (4.35) for the average probability of symbol error Pe by considering the following two cases: (a) po> P (b) Pi Po where po and p are the a priori probabilities of symbols 0 and 1, respectively. from appearing, and vice versa. Let po and p, denote the a priori probabilities of trans- symbols 0 and 1, respectively. Hence, the average probability of symbol error P in the receiver is given by A-A (4.35) No/T No opt-_ login (4.37)
