摘要: The non-linear distortion caused by high peak-to-average power ratio (PAPR) of transmitted signal is a major drawback in the OFDM systems. In this paper, proposed PAPR reduction scheme to choose corresponding symbol patterns with low ex- panded space. However, has complexity for selection pattern smallest larger expanded could be realized as mapping from original information symbols patterns. With corresponded patterns, greatly reduced. Ac- cording simulation results scheme, while length data frame 16 and expansion adding 1 bit 2 bits, changing rate 20 percents PAPA, respectively. there no prominent im- provement on more than 8 bits using scheme.
