- Sketch and accurately label the two signals.
- Draw and accurately label the simplest possible block diagram for the receiver which achieves the minimum probability of error.
- Compute the probability of error that you receiver achieves.
- Now assume that a receiver is used which simply integrates the received
signal between and . If the result is positive the receiver decides that
was transmitted, otherwise, if the integral is negative a decision in
favor of is made.

What is the probability of error for this receiver. - Clearly, the receiver in part (d) is the matched filter receiver if antipodal square pulses are used as the signal set. Give a good reason, why the designers of a communication system might prefer the signal set (2) over square pulses even though it leads to a somewhat more complex receiver.
