本附件包含在matlab环境下双谱分析源码的m文件，除了高阶谱，是用的比较广泛的一种。主要用于TDOA及弱信号检测等。可以动手下载后在matlab下运行之。和我前次发的高阶谱分析帖子一样，是要手动加入matlab高阶谱工具箱！

-This annex is included in the matlab environment bispectral analysis of source code of m documents, in addition to high-end spectrum, is widely used as a comparison. Mainly for TDOA and weak signal detection. Can begin download matlab running it. And my previous post issued order spectral analysis, is to manually add order spectrum matlab toolbox!
