Capitalizing on a well-known minimum mean square error (MMSE) property for decision feedback equalization (DFE) along with the use of stochastic gradient approach, we formulate an adaptive minimum error rate (MER) algorithm for DFE over M-ary PAM channels to be named as stochastic unbiased minimum mean error rate (SUMMER). Comparisons are made between SUMMER and existing MER algorithms in the literature and SUMMER is found to outperform others.
