A Novel PAPR Suppression Algorithm of Wavelet Modulation Signals

研究了小波包多载波调制信号的峰均比特点,提出了一种改进的小波包调制信号峰均比抑制算法。该方法具有发送端无需凿孔,接收端无需插值的特点,也就不需要一个附加的同步前向信道来传送标签信息,提高了频带利用率。仿真结果表明,所提出的方法可以有效降低小波包多载波调制信号的峰均比,且具有复杂度低,处理灵活,无需边信息等特点。

Peak to Average Power Ratio characters of wavelet modulation signals is analyzed. At first, we propose an improved PAPR suppression algorithm. The characteristic of this method is that puncture is not needed in the transmitting end, namely forward channel is not additionally employed to transmitted label information. The analysis and simulation indicate that the proposed method have the characteristic of low complexity, flexible disposing and disposing without side information.
