Blind SLM receiver for PAR reduced OFDM

Abstract — Selected mapping (SLM) gener-ates a set of independent signals from an infor-mation sequence and transmits the signal with minimum peak-to-average power ratio (PAR). To recover data, the receiver is sent criti-cal side information (SI) about the generation process. In this paper, a novel blind detec-tion algorithm is developed for coded orthog-onal frequency division multiplexing (OFDM) and SLM. The blind SLM algorithm performs well in both AWGN and fading channels in the presence of amplifier non-linearities. Key words- Maximum likelihood decoding, OFDM, pairwise error probability, peak-to
