Several widely linear equalization algorithms utilizing the rotationally variant nature of the received signals are pre sented in this paper to combat the detrimental effect of in tersymbol interference (ISI) introduced by frequency selec tive channels. Their adaptive implementations and appli cation to the time-reversal space-time coded (TR-STBC) system are also considered. In addition, a widely linear approach to turbo equalization is derived for systems em ploying error correction code. The widely linear equaliz ers and turbo equalizer are evaluated over broadband xed wireless access channels, and are shown to yield superior performance compared to the conventional linear schemes
