Optimal detection of coded differentially encoded QAM and PSK signals with diversity reception in correlated fast Rician fading channels

The optimal sequence estimator for digital signals received over Lambda different channels is derived. Each of these channels corrupts the transmitted signal by a mixture of additive white Gaussian noise (AWGN) and frequency-nonselective, correlated, fast Rician fading. By analysis it is shown that for the lth (1>
