Abstract—In this project proposed a phase offset selected mapping (SLM) Scheme is used to reduce PAPR which means Peak to Average Power Ratio for Alamouti coded Multi-Input &Multi-Output (MIMO) orthogonal Frequency Division Multiplexing System. The main key idea of this project is that different phase rotation sequence are multiplied by corresponding phase offset at a transmitter. Minimum Euclidean Distance (MED) decoder at the receiver will recover that phase rotation sequence. SLM scheme is not need to reserve bits for side band information due to this data rate is increased. Theoretical analysis and simulation results show that the proposed SLM scheme could offer good performances of both the bit error rate and PAPR reduction. Multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) has become a promising candidate for next generation broadband wireless communications a single-input single-output (SISO)-OFDM, one main disadvantage of the MIMO-OFDM is the high peak to- average power ratio (PAPR), which could be reduced by using an amplitude clipping.
