We consider joint source-channel and multiuser decoding for frequency-selective Rayleigh fading code-division multiple-access channels. The block source-channel encoder is defined by a vector quantizer, We investigate optimal (minimum mean-square error) decoding and user-separated decoding of lower complexity, The studied decoders are soft in the sense that they utilize all soft information available at the receiver. Simulations indicate significant performance gains of the introduced decoders compared with a tandem approach that uses maximum-likelihood multiuser detection plus table-lookup decoding.
