N2 - This paper proposes a deterministic nonlinear distortion suppression scheme employing transmit power control for MIMO-OFDM systems. The feature of the proposed scheme is to suppress the nonlinear distortion by adjusting the transmit power level of each transmit antenna to be the maximum signal-to-noise-plus-distortion ratio (SNDR) and to perform MIMO signal detection using the appropriate transmit power levels notified to the receiver. In the proposed scheme, since the transmit power tends to be lowered to satisfy the maximum theoretical SNDR, the transmit power as well as the bit error rate (BER) can be fortunately reduced in comparison with the traditional constant power transmission scheme, which consequently leads to alleviating the out-of-band radiation. The effectiveness of the proposed scheme is demonstrated compared with the traditional scheme with constant transmit power by means of computer simulations.
