CF-Based Adaptive PAPR Reduction Method for Eigenmode MIMO-OFDM Signals in Frequency-Selective Faded Channel
Yoshinari Sato, Kenichi Higuchi (Tokyo Univ. of Science) RCS2010-37
Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates a tradeoff between peak-to-average power ratio (PAPR) and achievable capacity of the proposed PAPR reduction method based on clipping and filtering (CF) for precoded orthogonal frequency division multiplexing (OFDM)-multiple-input multiple-output (MIMO) transmission in frequency-selective faded channel. While the conventional CF method adds roughly the same interference power to each of the transmission streams, the proposed method restricts the interference power applied to the streams that experience good channel conditions. Since the sum capacity is dominated by the capacity of the streams that experience good channel conditions and the interference caused by the PAPR reduction process severely degrades the achievable capacity of these streams, the proposed method can significantly improve the achievable sum capacity compared to the conventional CF method for a given PAPR. Simulation results elucidate that the proposed method significantly increases the capacity for given PAPR in comparison to that when using the conventional method, especially when the channel is frequency-selectively faded.
