Abstract
The authors propose a Bernoulli-Gaussian model based maximum-likelihood channel equalizer, which is a fixed-lag block signal detection algorithm, for binary channels in the presence of intersymbol interference and additive white Gaussian noise. The proposed equalizer not only performs as well as the maximum-likelihood sequence estimator via Viterbi algorithm but also allows the channel length to be infinite, and its computational load and storage are linearly rather than exponentially proportional to block size
