A system and method for reducing multi-path distortion of an M-ary communication signal is implemented with MxN parallel processors, a multi-path estimator, a metric selector and a decision processor. Parallel processors process each combination of possible signal symbols M and hypothesized guard times N, the output of the processors are supplied to the multi-path estimator which estimates the actual multi-path distortion of the transmitted symbol. The metric selector selects the processors with a guard time G<SUB>n </SUB>most closely approximating the estimate from the multi-path estimator. The selected outputs are used in a decision processor to determine the transmitted symbols. The selected outputs are low passed filtered.
