2. The output Y of a binary communication system is a unit-variance Gaussian (Normal) random variable with mean 0 when the input X is 0, and mean 1 when the input is 1. Assume that the input is 1 with probability p. (a) Determine fr(w). : If ( c) The receiver uses the following decision rule decide that input was 1; otherwise, decide that input was 0. Show that this decision rule leads to the following threshold rule: If Y...

3. (40 points) A binary communication system transmits signals s (0) (i = 1, 2). The receiver samples the received signal r(t) = s(t)+ n(t) at T and obtain the decision statistic r =r(T) = S(T) + n(T) = a, un, where the signal component is either a = + A or a, = -A with A >0 and n is the noise component. Assume that s (6) and s(l) are equally likely to be transmitted and the decision threshold...
