The advent of discrete multitone modulation (DMT) systems in recent years has brought to light the importance of channel shortening equalizers. In this paper, we present a method for the design of one such equalizer for multiple-input multiple-output (MIMO) linear dispersive channels. This method is a generalization of one that was used for shortening of single-input single-output (SISO) channels. Experimental results presented show that our design method performs better than the minimum mean-squared error (MMSE) technique in terms of effective channel energy compaction. 1
