We consider the problem of single user trellis decoding in a multiuser CDMA communications system. A multiuser device is proposed to provide the single user decoders with metrics from which they construct path metrics. In the proposal the multiuser device generates Maximum A-Posteriori (MAP) probabilities for codeword bits and is non-linear in nature. Path metrics are then constructed in the single user decoders by considering streams of these probabilities. The performance of the MAP scheme is… CONTINUE READING
