摘要
本文针对单载波和多载波信号的类间识别,使用DB3小波分解提取待识别信号的特征向量,研究分析经过短波监听系统截获的实际传输信号。结果表明,所提取的特征向量在识别实际采样信号时具有良好的性能。
This paper discusses the inere-class recogniton of Multi carrier signal and Single carrier signal which is intercepted by Shortwave monitoring system. In this paper, the dB3 wavelet is used for feature extraction. Simulation results shows that the proposed feature classifer have good performances in actual signals.
