Abstract:
A multi-user detector processing system for multiple access communications channels, comprising:a multi-user detector coupled to a plurality of user signals, wherein said multi-user detector produces a first set of symbol estimates for each of said user signals; a first bank of decoders coupled to said symbol estimates producing a first decoded data stream; and a second bank of decoders coupled to said first bank of decoders processing said first decoded data stream and producing a second decoded data stream, wherein said second decoded data stream is passed back to said first bank of decoders for processing of a third decoded data stream, wherein said third decoded data stream is passed back to said multi-user detector for processing of a second set of symbol estimates for each of said user signals, and wherein said second set of symbol estimates is passed to said first bank of decoders to produce a fourth decoded data stream said fourth decoded data stream is passed to said second bank of decoders to produce a fifth decoded data stream.
