中文说明：信号处理中的旋转不变子空间法，采用的是通用的平面波展开法,保证准确无误，是学习通信的好帮手，基于互功率谱的时延估计，已经调试成功.内含m文件，可直接运行，关于神经网络控制。
English Description：
Rotation-invariant subspace methods in signal processing, using the plane wave expansion method is common to ensure accurate, is a good helper for learning communication, based on cross power spectrum time delay estimation, had successfully. contains m file, and can be directly run on neural network control.
