摘要：

We examine coding/decoding schemes matched to a "vertical" BLAST architecture. We assume a code whose words are evenly split among the transmit antennas The subcodes transmitted by each antenna are decoded in sequence to cancel the spatial interference, while a final decoding step is performed on the whole code. We also examine the behavior of zero-forcing (ZF) and minimum-mean-square error (MMSE) BLAST by comparing their error probabilities with those resulting from optimum, i.e., maximum-likelihood (ML), processing. Since with vertical BLAST ordering of the columns of the channel-gain matrix is crucial, we also study the Performance of algorithms intended to find an optimal (or mildly suboptimal) ordering.
