A combined scheme for PAPR reduction in OFDM system

A combined scheme for PAPR(peak-to-average power ratio) reduction in OFDM(orthogonal frequency division multiplexing) system is proposed.The PAPR can be reduced twice by using SLM(selected mapping) technique and compounding technique.Simulation results show this method can get better PAPR performance than using the above techniques alone.In the OFDM system which has not too much requirement in computational complexity,the schemes with different parameters can be replaced each other to obtain better BER performance.
