这个是多相滤波的MATLAB程序，做接收机的同学可以参考的(this is a polyphase programme)

DigiPic 函数主要功能是将一个图片形式的表格函数,获取其数据,拟合为一个解析式. 便于计算机使用 DigiPic功能描述 在matlab 2013a运行环境下,启动DigiPic 首先,导入要分析的图表照片 取点建立坐标系,坐标系在取点时同时输入对应的实际坐标值, 拖拽坐标点使其位置在图片上尽量准确,便于后面坐标的自动计算. 按右键完成坐标系的建立. 在图片上原函数图线处取点.同时自动计算函数值 在拟合页,导入函数数据.选择相应的拟合函数.自动计算出最佳参数. 在拟合前,可人工在函数列表中修改,设定参赛,使计算更快. 选择保存目录,保存数据.数据以excel文件保存,图片和数据文件最好放在一个目录里. excel文件数据可直接在其它分析软件中使用. 打开原分析文件时,可同时打开多个.( DigiPic function main function is to form an image in the form of a function, to get their data, fitting of an analytical style. To facilitate computer use DigiPic Description operating environment in matlab 2013a, start DigiPic First, import to be analyzed Charts Photos access point to establish a coordinate system, the coordinate system at the access point simultaneously enter the actual coordinate values ​ ​ corresponding to the coordinates of the point drag on the image to make it as accurate as possible location, easy to automatically calculate the coordinates back. completed by the right coordinates established. Uehara function graph in the picture at the access point. while automatically calculated in the fitting function value page data import function. choose the appropriate fitting function. automatically calculate the optimal parameters. before fitting, artificial modification in the function list, set the entry to make computing faster. choose to save)

FH Spread Spectrum System simulation in MATLAB

Distributed Beamforming for Relay Networks Based on Second-Order Statistics of the Channel Statement Information最小发送功率与最大信噪比的代码，结果与论文中相同，总共9个仿真图(Networks Based on Second-Order Statistics of the Channel Statement Information。Minimum transmit power with maximum signal-to-noise ratio of the code, the same results paper, a total of nine simulation Figure)

为支持向量机代码，源代码为matlab实现，可以做聚类问题(To support vector machine codes)

说明：  信号处理，误差曲面的优化和误差最小点的寻找(Signal processing, optimization of the error surface and error to find the minimum point)
