摘      要：Orthogonal frequency division multiplexing （OFDM） has increasing popularity due to its high spectrum efficiency,high data transmission and resisting channel ***,high peak-to-average power ratio （PAPR） is a dominating obstacle in OFDM systems,which degrades the system *** this paper,a kind of new phase sequences combined with selective mapping algorithm （SLM） is *** results show that the improved approach effectively reduces the PAPR,and the BER performance is nearly as the same as the original OFDM system without PAPR reduction measures.
