Clipping and Filtering-Based PAPR Reduction Method for Precoded OFDM-MIMO Signals

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a new peak-to-average power ratio (PAPR) reduction method based on the clipping and filtering for precoded orthogonal frequency division multiplexing (OFDM) - multiple-input multiple-output (MIMO) transmission. While the conventional clipping and filtering method adds roughly the same interference power on each of the transmission streams, the proposed method restricts the interference power application to the streams in good channel conditions. Since the sum capacity is dominated by the capacity of the streams in good channel conditions and the interference caused by PAPR reduction process severely degrades the achievable capacity for these streams, the proposed method can largely improve the achievable sum capacity compared to the conventional clipping and filtering method for a given PAPR. Simulation results demonstrate the capacity gain by using the proposed method compared to the conventional method.
