Unformatted text preview: n has a normal distribution with a mean of 3V and a variance of 5V 2 . Assume that the prior probability for transmitting s 1 is given by P 1 = 0.25 and for s 1 is given by P 2 = 0.75. (a) [5 points] Starting with the maximum likelihood (ML) ratio test 1 2 2 1 2 1 ) ( ) ( P P s z p s z p s s z z < > where p z ( z  s 1 ) and p z ( z  s 2 ) are the conditions pdfs on s 1 and s 2 respectively, derive the ML detector for the receiver. (b) [5 points] Determine the probability of error for the detector designed in part (a)....
