IIR_digital_filter

说明：  该程序基于BP神经网络编程，开发工具MATLAB用于预测(The program based on BP neural network programming, development tools, MATLAB used to predict)

FRACTIONAL FORUIER TRANSFORM MATLAB PROGRAM

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)

给出了reliefF算法的matlab源代码，该算法用于处理目标属性为连续值的回归问题。是由relief算法拓展所得，可以处理多类别问题。(ReliefF algorithm matlab source code is given, and the algorithm is used for processing target attribute is continuous values of regression problems.By expanding income relief algorithm, can deal with many categories.)

发送端统一使用4根发送天线,通过改变接收天线的数目来比较不同数目的接收天线对空间调制（spatial modulation）系统性能的影响。(Sending uniform use of four transmission antennas, by changing the number of reception antennas to compare the different number of receiving antennas for spatial modulation (spatial modulation) system performance.)

主要是利用转换域算法来进行OFDM信道估计，并将其与LS算法进行比较(Transform domain algorithm for OFDM channel estimation, and comparison with the LS algorithm)

3d金属波导TE、TM模式计算及模拟作图(3d metal waveguide TE, TM mode calculation and simulation mapping)

应用MATLAB语言处理数字信号与数字图像，里面 有matlab调用c的方法(Application of MATLAB language processing digital signal with the digital image, which has matlab call method c)

说明：  偏最小二乘法中的交叉有效性计算的matlab程序，怎么计算出来的预测误差平方和PRESS不太对，偏大；()

code for full estimation of disparity map from two right and left image
