摘要 正交频分复用(OFDM)技术的一个主要缺点就是传输信号的峰值平均功率比(PAPR)较高。部分传输序列(PTS)技术是一种无失真的降低PAPR的有效方法,但其复杂度较高。提出了一种用滑动窗搜索辅助信息的次最优PTS方法,仿真结果表明,该方法能够较好地解决系统复杂度与降低PAPR的问题。 One of the major drawbacks of orthogonal frequency division multiplexing （OFDM） is the high peak-to-average power ratio （PAPR） of the transmitted OFDM signal. Partial transmit sequence （PTS） is a kind of undistorted method to reduce the PAPR effectively but with high complexity. A sliding window based PTS factor searching method is proposed. Simulation results show that this method can obtain good trade-offs between complexity and performance on PAPR reduction using PTS schemes.
