Abstract :
The optimal blind maximum a posteriori symbol detection (MAPSD) algorithm for spatial diversity combining is derived. This diversity MAPSD (DMAPSD) algorithm is applied to a time division multiple access (TDMA) system for the recovery of mobile radio signals. Lower complexity DMAPSD algorithms are described, and their error rate performance for fast fading channels is studied via computer simulations. The results indicate that the proposed MAP detectors provide SNR gains of 6-13 dB over a zero-forcing decision-feedback equalizer (DFE)
