Abstract
In this paper, an expectation-maximization technique for maximum a posterio ri estimation is employed to devise novel soft-in soft-out algorithms for s ymbol detection over frequency-flat Rayleigh fading channels. An applicatio n of these algorithms to iterative decoding of coded PSK signals is propose d and some performance results are illustrated.
