A Modified Selective Mapping with PAPR Reduction and Error Correction in OFDM Systems

This paper proposed a PAPR reduction method for BPSK OFDM systems and 16-QAM OFDM systems respectively. The strategy of the algorithms is to use a correction subcode for error control and a scrambling subcode for PAPR control. The transmitted OFDM sequence is selected with minimum PAPR from a number of candidates which form a coset of scrambling subcode for each codeword of correction subcode. In a BPSK OFDM system, the PAPR reduction is obtained by combining the SLM method with binary cyclic codes. In a 16-QAM OFDM system, the PAPR reduction is achieved by combining the SLM with block coded modulation. The received signal of the modified SLM can be decoded without the need of explicit side information and the proposed scheme achieves good PAPR reduction.
