Abstract :
In this paper, optimal detection of PSK signals with pilot symbol assisted modulation (PSAM) in Rayleigh frequency-flat fast fading channels is investigated. We prove that in spatially uncorrelated single-input multiple-output channels, the optimal symbol-by-symbol detector is equivalent to a mismatched detector with minimum mean square error (MMSE) channel estimation. However, this is not the case for signals with non-constant envelope and/or multi-antenna transmission.
