| 摘 要： | 针对正交频分复用(OFDM)信号峰均比(PAPR)高的问题,提出了一种降低PAPR的融合算法,通过在发射端对OFDM信号进行两次降低PAPR处理来降低系统的峰均比.仿真结果表明,该算法可以大幅度的降低OFDM信号的PAPR.

| Abstract: | In order to reduce the high peak-to-average-power-ratio(PAPR) of OFDM signal,a combined scheme which reduces two times the PAPR of OFDM signal is proposed in this paper.The simulation results verify the much improved performance of PAPR using this approach. |
