This paper brings some noticeable improvements to a blind decison feedback equalizer recently introduced and mainly characterized by its self-adapted structure. In its starting-up mode, this equalizer is linear and recursive and controlled by a whitening criterion for the recursive part and the Godard criterion for the transversal one. However, in the case of high order QAM signals, the whole p...

The two criteria most commonly used in blind equalization are Sato's cost function and Godard's cost function. In this paper we analyze a sign-error cost function for real signals which gives an error term that can be viewed as the sign of either the Sato or the Godard error. We show that the conventional de nition of equalizer convergence is not suitable for analyzing this cost function. A mor...
