On linear H∞ equalization of communication channels

As an alternative to existing techniques and algorithms, we investigate the merit of the H∞ approach to the linear equalization of communication channels. We first give the formulation of all causal H∞ equalizers using the results of [1] and then look at the finite delay case. We compare the risk sensitive, H∞ equalizer with the MMSE equalizer with respect to both the average and the worst case BER performances and illustrate the improvement due to the use of the H∞ equalizer.
