Matlab和Labview混合编程，可以演示信号的白噪声添加和滤波，以及时域和傅立叶变换后的频域波形(Matlab and Labview mixed programming, you can demo the white noise signal add and filtering, as well as the time-domain and Fourier transformed frequency domain waveform)

基于能量分离语音，声场景方面的。其实是更好的分段，算是预处理吧(Based on the energy separation of voice, sound and scene.)

对人行走时的微动特性进行了分析，采用时频分析技术展示了人行走的微多普勒效应，与国外相应分析文章结论一致。(Fretting characteristics of people walking were analyzed, using frequency analysis when the micro-Doppler effect shows people walking, consistent with the analysis of the article corresponding foreign conclusions)

说明：  noma simulation programme in matlab

说明：  kpca的matlab源码，只要有人脸库就可用！(kpca of matlab source, as long as people face database can be used!)
