Abstract
The selected mapping (SLM) scheme is one of the well-known peak-to-average power ratio (PAPR) reduction schemes for orthogonal frequency division multiplexing (OFDM) systems. A number of low-complexity SLM schemes have been proposed but most of them reduce the computational complexity at the cost of bit error rate (BER) or PAPR reduction performance degradation. In this paper, a new low-complexity SLM scheme is proposed, which generates alternative signal sequences by adding mapping signal sequences to an OFDM signal sequence. The proposed scheme considerably reduces the computational complexity without sacrificing BER and PAPR reduction performance only by requiring additional memory to save the additive mapping signal sequences, especially for the OFDM system with quadrature amplitude modulation (QAM). Similarly, a low-complexity SLM scheme is proposed for multi-input multi-output (MIMO) OFDM system with space-frequency block code (SFBC).
