Claim One:
1. A hybrid Multi-User Detector for processing a plurality of received signals, comprising: a parameter estimation unit coupled to said received signals; a high complexity multi-user detector coupled to said parameter estimation unit, wherein said high complexity multi-user detector performs a pruned tree search and outputs a plurality of information streams, one stream corresponding to each of said received signals; a bank of high complexity decoders coupled to said plurality of information streams, wherein said high complexity decoders output a plurality of refined information streams; a low complexity multi-user detector coupled to said bank of high complexity decoders, said plurality of refined information streams, and said parameter estimation unit, wherein said low complexity multi-user detector outputs a plurality of improved information streams; and a bank of error correction decoders coupled to said plurality of improved information streams, wherein said error correction decoders output a plurality of refined-improved information streams, said plurality of refined-improved information streams fed back to said low complexity multi-user detector until a final condition is reached and said bank of error correction decoders output a final plurality of symbol streams.
