| 摘 要： | 针对阈值限幅法误码率极大和部分传输序列(PTS)技术复杂度高的问题,提出一种改进的基于阈值限幅和PTS技术的正交小波包复用(OWPM)系统高峰均功率比(PAPR)降低方法.仿真结果表明:改进后的算法性能得到提升,且经阈值限幅法和PTS技术联合处理后,能够在尽量不影响原系统误码率性能的前提下,更好地降低系统PAPR值,同时也降低了系统计算复杂度.

| Abstract: | Aiming at the problem of large BER for the threshold clipping method and the high computational complexity for partial transmit sequence(PTS)technology, an improved peak to average power ratio(PAPR)reduction method based on the threshold clipping and PTS technology for orthogonal wavelet packet multiplexing(OWPM)system is put forward in the paper. Simulation results show that the improved algorithm compared with the original algorithm has the corresponding performance improvement, and by the combined treatment with threshold clipping method and PTS technology, in the premise of not affectting the original system BER performance, better reduce the system PAPR value, while reducing system computational complexity. |
