Signal rreowr! in that rase is not obvious. Different methods with different performances have been suggestcd. F r o m il statistical analysis of wrvrs a t the outpiit o f Zero-Forcing, we have constructed a method. which w c present in this article. that combines Zero-Fvrcing and hlarimum Likelihood. We will demonstrate that it provides bath a lo\% complexity and nearly aplimal results regarding Binary Error Rare (BER). Furthermore. w e will show its rele\.;tnr> compared to t h e YBLAST algorithm.
