Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a clipping and filtering method employing transmit power control in OFDM transmission to combat the bit error rate (BER) degradation due to the nonlinear distortion. 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. Moreover, the effectiveness of the proposed method is demonstrated in comparison with the traditional clipping and filtering method with the constant transmit power level.
