Unformatted text preview: s /N in db. 3. Find an expression for the union bound for the probability of symbol error for a 32 point QAM signal constellation. Make the usual assumptions about AWGN, equally likely signals, optimal receiver, etc. Plot your result versus E b /N in db. (Note: Now we use E b / N .) 4. Do a simulation to verify the result found in problem 3 for an E b /N that gives a symbol error rate of about 10-3 . 5. For M even, consider a signal set of M signal consisting of M/2 equi-energy orthogonal signals and their negatives. Make the usual assumptions about AWGN, equally likely signals, optimal receiver, etc. Derive an expression for the probability of symbol error versus E s /N in db. Like in the case of M orthogonal signals, you can leave your result in terms of a multi-dimensional integral....
