A low-complexity data-derived iterative channel estimator is evaluated in a receive diversity system for two and four receive antennas. The performance is shown almost to match the ideal (perfect channel knowledge) case in a low-Doppler environment. At higher Doppler frequencies, performance is still good, but deviates from the ideal case. A Wiener filter tracking algorithm is proposed that is advantageous at lower E/sub b//N/sub 0/ ranges, however linear tracking is found to be better at higher E/sub b//N/sub 0/ ratios and therefore further improves performance for higher order modulation schemes such as 16-QAM.
