独立成分分析方法对时相调制信号的特征提取
Feature extraction of time-phase modulation signals by independent component analysis
摘要
Abstract
In time-phase modulation systems,the aliasing signals of multi-channel time-phase modulation signals received at the multiple sensor ports are separated into relatively independent segments by adopting the fast Independent Component Analysis (ICA)algorithm so that their phase abrupt features can be extracted and their detection and demodulation accomplished.Simu-lation results indicate that this technique can extract the phase abrupt features of time-phase modulation signals with distinct effects.关键词
