Space Division Multiple Access in conjunction with OFDM results in a robust system that increases spectral efficiency and system capacity. This combination is positioning as one of the most promising candidates for future WLAN implementations. One drawback of OFDM systems is the high peak to average power ratio, which imposes severe requirements for the linearity of the power amplifier (PA). Such linearity requirements translate into high back-off resulting in low power efficiency. In order to improve power efficiency, power amplifier nonlinearity cancellation is introduced. This technique reduces the nonlinear distortion over the recovered symbols. The performance of the novel structure is evaluated with simulations giving power efficiency improvements in the order of 30 %. Also simulation results shows the robustness of the cancellation technique at channel estimation accuracy. |
