Description/Abstract
The performance of burst-by-burst adaptive modulation is studied in conjunction with reduced complexity turbo equalization over a wideband multi-path Rayleigh fading channel. By employing the reduced complexity turbo equalizer, higher-order modulation modes such as 64-level Quadrature Amplitude Modulation (64-QAM) can be invoked, than upon using the conventional turbo equalizer. The structure of the reduced complexity turbo equalizer was also exploited in order to invoke an iterative least mean square channel estimator. Finally, the performance of the adaptive modulation scheme was compared to that of its constituent modulation modes and a signal-to-noise ratio gain of 1.0dB to 1.5dB was recorded for the throughput range of 0.5 to 2.0 bits/symbol.
