EE 522 - Communication Theorys - Spring 2010 Homework #4 - Optimum Receiver Design Assigned: Thursday, March 11 Due: Thursday, March 18 1) Consider the signal constellation from problem 1 of homework #3. (a) Sketch a block diagram of the optimum receiver for this signal constellation that is implemented by correlating with each signal. Give numerical values for all parameters. (b) Sketch a block diagram of the optimum receiver for this constellation that is implemented by correlating with each basis function. Give numerical values for all parameters. (c) Sketch a block diagram of the optimum receiver for this constellation that is implemented with matched filters for each basis function. Give numerical values for all parameters and sketch the impulse
