Selected mapping (SLM) is an attractive, non-distortion technique to reduce the PAPR of OFDM signal. The conventional SLM method requires the transmission of side information i.e. the index of the selected signal (with lowest PAPR) with each OFDM symbol. This leads to reduction in data rate loss. In this paper we have proposed two new phase sequence sets (i) modified binary chaotic sequence and (ii) modified Hadamard sequence for SLM-OFDM system based on quaternary modulation and suggested a new mapping scheme called "Rectangular Mapping" to map the Quaternary data to 8-PSK constellation by using two phase factors {1, j} to eliminate the requirement of SI. The proposed method provides good PAPR reduction in comparison to existing SLM schemes and provides consistent SER performance as SI is not required.
