In this study, it is argued that the minimum mean-square-error (MMSE) adaptation mechanism in the presence of error propagation will find a better answer than the solution computed in the absence of decision errors. Error propagation is enhanced by large gains in the decision portion of the decision feedback equalization (DFE) portion. A method to penalize these gains is considered, but not in the unconstrained MSE sense.
