Selected mapping with monomial phase rotations for peak-to-average power ratio reduction in OFDM

Selected mapping (SLM) is a promising technique to reduce the high peak-to-average power ratio (PAR) of OFDM signals. In this paper, we propose a novel concept of using monomial phase sequences for SLM. The selected monomial phase parameter is not transmitted as side information, but can be detected at the receiver. We demonstrate that it is possible to achieve significant PAR reduction with no loss of information rate and little degradation in the symbol error rate. The cubic phase sequence is found particularly suitable for this application.
