PTS scheme using additive mapping sequence for peak power reduction in OFDM systems

Abstract

In this paper, a new low-complexity partial transmit sequence (PTS) scheme is proposed, which generates alternative signal sequences by adding mapping signal sequences of each subblock to each signal subsequence. The proposed scheme considerably reduces the computational complexity without sacrificing BER and PAPR reduction performance, especially for the OFDM system with quadrature amplitude modulation (QAM).
