独立分量分析（ICA）以非高斯源信号为研究对象，在统计独立的假设下，对多路观测到的混合信号进行盲信号分离，已广泛应用于无线通信、生物信号提取、语音信号处理、图像处理和噪声抑制等领域。 (The independent component analysis (ICA) addresses non-Gaussian source signals under amusing independent each other, it performs blind separation for multi-channel observed signals. It has widely applied in wireless communication, biological signals extraction, audio signal processing, image processing, and noise reducing and so on.)

基二的fft算法仿真，和matlab中fft( , )函数性能没什么差别！(II fft algorithm based simulation, and matlab in fft (,) function no difference in performance!)

可以简单的实现快速傅里叶变换，这只是部分的，等开通了账号再把其他的上传上来(Can simply fast Fourier transform)
