Abstract

We develop a blind recursive equalizer by exploiting space-time structure inherent in array observations of several co-channel digital communication signals which we assume are encoded prior to transmission. The redundancy present in coded signals offers additional structure which can be exploited to enhance recovery of the transmitted symbols. Through simulations, we evaluate the relative advantages of exploiting the code structure.
