摘要
文章利用盲源分离技术试图从给定的一组混合观察数据中恢复未知的独立信源。然后使用Matlab中的时频工具箱,根据分离出的信号进行时频分析,提取信号中所包含的特征信息,达到能够识别出期望信号,并能提取其余干扰信号的特征。
Unknown independent sources from a given set of observed mixtures are recovered using a blind source separation technique. Time and frequency analysis on the separated signals is then conducted using Matlab toolboxes for time and frequency domain processing to extract diagnostic information, through which the expected signal is recognized, and characteristics of interference signals extracted.
