Abstract

This paper addresses the misconvergence associated with the transient performance of blind adaptive equalizers, in the context of mobile communications. Detection of misconvergence is carried out based on several methods for the estimation of the bit-error rate (BER) at the output of the blind equalizer, thus leading to new countermeasures in order to overcome channel effects on the equalizer performance. A comparative study of several detection techniques is carried out for both static and dynamic channels. Simulations point out the effectiveness of the new misconvergence management methods.
