ABSTRACT

One major Disadvantage of OFDM is the high peak-to-average Power ratio (PAPR). One investigated technique Selected Mapping (SLM) is PAPR reduction techniques for Orthogonal Frequency Division Multiplexing (OFDM). In this paper we proposed a Modernize SLM (MSLM) scheme to reduce the PAPR by using the complex signal to separate into real & imaginary parts and use as a individually phase sequence multiply real part as well as imaginary part of complex signal. Finally select the minimum PAPR signal of real & imaginary part and combine both of the approach. The simulation show achieves good PAPR. , which is one of the strong candidate for Future wireless communication.

Keywords: OFDM, PAPR, SLM and MSLM.
