E. Chiavaccini et Gm. Vitetta, MAP symbol estimation on frequency-flat Rayleigh fading channels via a Bayesian EM algorithm, IEEE COMMUN, 49(11), 2001, pp. 1869-1872
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.
