Companding schemes based on transforming signal statistics into trigonal distributions for PAPR reduction in OFDM systems

摘要

This paper proposes four companding transforms to reduce the peak-to-average power ratio in orthogonal frequency division multiplexing systems. The four companding transforms are obtained by transforming signal statistics into four trigonal distributions. Computer simulations show that the proposed schemes can effectively improve the PAPR performance and bit error rate performance of OFDM systems.
