Unformatted text preview: (b) Calculate the conditional probability of symbol error, conditioned on the i th signal being transmitted for i = 0, 1, 2, 3, and 4. In each case express your answer in terms of E b /N . (c) Calculate the average probability of symbol error, P s . Again express your answer in terms of E b /N . Note: If you think real hard you will be able to get an exact expression for P[symbol errors i (t) was transmitted] for i=1, 2, 3, and 4. If you cant, get an upper bound and a lower bound for these probabilities and for P s ....
