MATLAB6_5

这是一款有用的DOA估计算法，可以有效地通过驱动向量估计出DOA(This is a useful DOA estimation algorithm can effectively estimate the DOA vector through the drive)

PROGRAM IS USED FOR PARALLEL PORT CHECKING WITH HELP OF MATLAB.

对已经调制的信号进行相干解调，然后观察频域特性(The modulated signal for coherent demodulation, and then observe the frequency domain characteristics)

双通道的频分多址技术的SIMULINK仿真模型(Dual-channel frequency division multiple access technology, SIMULINK simulation model)

说明：  用MATLAB实现支持向量机程序，有训练集和测试集，程序完整。(Using MATLAB support vector machine procedures to achieve, there are training set and test set, the program integrity.)

自己编的，基于自然梯度的盲源分离算法，如果想对自然梯度有所了解，可以参考Amari的经典文章。网络上一搜就行。(own series, based on the natural gradient algorithm blind source separation, if you want to understand the natural gradient. Amari can refer to the classic article. Networks found on a trip.)
