Abstract :
In this study, we investigate the practical effect of nonlinear channel distortion on Alamouti space-time coded MIMO-OFDM signals. In particular, we consider a slow fading environment under which the performance of an iterative nonlinear distortion cancellation algorithm is studied. Furthermore, an adaptive MIMO-OFDM system is also proposed in conjunction with iterative noise cancellation to combat the nonlinear channel distortion effects on MIMO-OFDM signals.
