Abstract

MU-MIMO-OFDM is an effective technique to achieve high capacity and reliable wireless communications systems because both the robustness against multipath fading and the high spectrum efficiency can be effectively achieved by the combination of OFDM with MU-MIMO. However, MU-MIMO-OFDM significantly suffers from the nonlinear distortion which is a main drawback of OFDM. In this paper, we propose nonlinear distortion suppression scheme employing transmit power control for MU-MIMO-OFDM. The main feature of the proposed scheme is to apply the deterministic transmit power control to MU-MIMO-OFDM without any destruction of the space orthogonality. The effectiveness of the proposed scheme is demonstrated in comparison with the traditional MU-MIMO-OFDM over the nonlinear fading channels.
