Multi-channel MLSE equalizer with parametric FIR channel identification

We propose an optimal multi-channel MLSE equalizer (using multiple antennas) with parametric FIR channel identification, and investigate the effects of this algorithm on the overall BER performance in the TDMA system. By exploring the structure of the specular multi-path Rayleigh-fading channels, we are able to reduce the number of unknown parameters to provide a better channel estimate for the MLSE equalizer. An analytic BER lower bound for the general linear modulation schemes in the specular multi-path Rayleigh-fading channels is derived. Some simulation results that illustrate the performance of the proposed algorithm in the GSM system are also presented and compared to the analytic lower bound.
