Abstract

This article presents a new procedure to detect equalization errors in time-varying channels (TVC). This procedure has low computational complexity and can be used with different modulation or equalization schemes. In order to detect the occurrence of errors a test of hypothesis is performed using a proper measure of distance between decision-directed channel estimates produced by two adaptive filters with distinct characteristics of robustness to the use of erroneous references. Several results of performance evaluation by simulation are presented and indicate the effectiveness of the proposed scheme.
