Abstract:
This paper investigates the effects of Non-linear amplifications on the performance of space-time coding systems. Pairwise Error Probability (PWEP) and Bit Error Probability (BEP) performance of 16-states space-time codes employing 16-QAM signals over linear and nonlinear MIMO channels are presented. Performance degradation due to non-linear amplifications of the transmitted coded symbols are then evaluated. The results show significant performance degradations when spacetime codes operate over nonlinear MIMO channels.
