This paper proposes a novel clipping and filtering method employing transmit power control to improve the bit error rate (BER) performance in MIMO-OFDM transmission. The feature of the proposed approach is to perform the transmit power control before clipping and filtering to alleviate the BER degradation caused by clipping and filtering. Since the transmit power control to satisfy maximum signal-to-noise-plus-distortion ratio (SNDR) tends to lower the transmit power level especially in a relatively large CNR, the combination of its transmit power control with clipping and filtering surely improves the BER performance while suppressing the out-of-band radiation. Considering that MIMO systems suffer from the nonlinear distortion much more than SISO systems, the performance evaluation is to be conducted on MIMO systems, and the effectiveness of the proposed approach is demonstrated in comparison with the traditional clipping and filtering method with the constant transmit power level.
