Comments on `A decision feedback recurrent neural equalizer as an infinite impulse response filter'

Abstract

This correspondence corrects and clarifies some notation inconsistencies and the absence of some definitions in a previous paper by Ong et al.. In addition, we show that the assumptions made in the derivation of the MSEDFRNE-MSERNE invalidate the final result given in Ong et al. and lead to an unfair comparison between the two equalizers. We present a simulation that best compares the two equalizers.
