Abstract : The channel capacity achievable for M-ary transmission over a Rayleigh fading channel is analyzed for the Wozencraft-Kennedy list-detection scheme. Calculated capacities are given for both list-detection and decision-detection for several SNRs and for several alphabet sizes ranging up to 4096. In addition, small and large SNR asymptotic expressions for the capacity are given for decision-detection, list-detection and likelihood-detection. The maximum capacity for arbitrarily large alphabet size is determined. (Author)
