| 摘 要： | 小波调制信号是一种特殊的调制信号,该文基于小波调制信号独特的时频特征,利用自适应优化核时频分布方法,探讨基于时频混合矩的多载波调制信号的识别。仿真表明,该方法不仅能将小波调制与OFDM信号进行分类,同时还能对不同调制级的小波调制信号进行分类。

| Abstract: | Wavelet modulation(WM) signal is a special kind of modulation signal.Based on the time-frequency characteristics of WM signal,this paper uses the adaptive optimal kernel(AOK) time-frequency analysis method to discuss the identification method of multi-carrier modulation signals with the mixed moments of AOK time-fre-quency distribution as classification feature.Simulation results show that,this method can not only separate wavelet modulation signal from OFDM signal,but also can identify wavelet modulation s... |
