摘要

小波包分复用(WPDM)是一种很有前途的多路信号传输技术，它将报文信号以波形编码到小波包基函数上。它是为了保证在恶劣环境下更好的传输质量而提出的。本文通过对峰值平均功率比(PAPR)准则的分析，丰富了前人的研究。在此基础上，提出了基于最佳小波包基函数选择和不同用户映射的方法来降低PAPR。进行了一些模拟来支持分析。

PAPR analysis and reduction in WPDM systems

Wavelet packet division multiplexing (WPDM), in which the message signals are waveform coded onto wavelet packet basis function, is a promising technique for multiple signals transmission. It was proposed in order to ensure better transmission quality in hostile environments. In this paper, we enrich previous studies by analyzing the peak to average power ratio (PAPR.) criterion. A procedure based on best wavelet packet basis function selection and different users mapping is then proposed in order to decrease the PAPR. Some simulations are carried to support the analysis.
