Abstract
We examine the error rate performance of various equalizers on two nonlinear channel models which have been proposed recently in the literature: a partial erasure model and a Volterra model. We find that when the noise is appreciable the performance of the Volterra equalizer is only slightly better than that of a linear equalizer. Our results also demonstrate that write precompensation for transition shift elimination is to be preferred over post-compensation
