Orthogonal Frequency Division Multiplexing (OFDM) is a robust and effective multicarrier transmission technique for high speed communication in the wireless mobile environment and applications. A major challenging issue in the application of OFDM is its high peak to average ratio (PAPR). The Selective Mapping (SLM) is one of the promising techniques which offer a distortion less PAPR reduction at the cost of bandwidth efficiency and computational complexity. The rows of the Hadamard, Riemann and the Centering matrices are suggested to be used as the phase sequences in the literature. In this research work, the original SLM scheme is modified by using the new phase sequences, which are the combinations of the circulating matrix along with the Hadamard and the Riemann matrices. The simulation results show that the proposed phase sequences offer an improved PAPR reduction and thus outperform some of the previously proposed techniques..
