Equalizers in digital communications systems are typically designed to shape the channel frequency response so as to minimize the mean square error between the received and transmitted symbol sequences, given some coded or uncoded modulation scheme. Here we investigate the possibility of simultaneously optimizing both the modulation/coding scheme at the transmitter and the channel dispersion characteristics. The optimality criterion used is minimum L2-distance between channel outputs. This may be useful in situations where channel characteristics can be manipulated by the designer. Furthermore, the performance of the optimized system can be used as a benchmark by which to compare the performance of coding and modulation schemes with suboptimal channels.
