Abstract

In MIMO space division multIPlexing (SDM) systems, the peak power of the transmit signal at each antenna element is increased by the precoder and hence it causes the power efficiency degradation and/or nonlinear distortion at the power amplifier. To solve this problem, this paper present a peak power aware precoding scheme for MIMO-SDM systems, where the precoder is designed to mitigate the peak output power at each antenna element so that peak amplitude of the transmit signal at each antenna is reduced while minimizing the performance degradation caused by the peak power restriction. The proposed system employs an aLTErnative iterative optimization algorithm that determines the precoding matrix so that the precoding and virtual post-coding matrices are aLTErnatively optimized under the constraint of peak output at each antenna element. Simulation results show that the proposed method is effective in restricting the peak transmission power at each antenna within a permissible level while mitigating performance degradation in bit error rate (BER) performance of the precoded SDM systems.
