Abstract :
This paper investigates the performance of MIMO subset antenna selection systems over nonlinear fading channels. Pairwise error probability (PWEP) performance of 16-states space-time codes with antenna selections are derived over nonlinear MIMO channels. Performance degradations due to non-linear amplifications of the transmitted coded symbols are then evaluated for the reduced-complexity systems. The results show that the performance degradations, due to nonlinearity in the channels, reduce as less numbers of antennas are selected, representing some savings in SNR penalty due to nonlinearity for the reduced-complexity system
