说明：  文件为灰色建模的Matlab程序，供大家参考学习，希望互相交流，共同进步。(documents gray Matlab modeling procedures for reference learning, hope mutual exchanges and common progress.)

通信系统仿真原理与无线应用配套MATLAB代码(Wireless communications system simulation theory and applications supporting MATLAB code)

基于matlab的4种梯度算子，Sobel Operator、Laplacian Operator、Prewitt Operator等等(Matlab based on the four kinds of gradient operator)

说明：  matpowe3.1b2 Open source software, no modified version downloaded from the official website, different matpower may not apply with each other program

Reads TDMS files into Matlab. See TDMS_exampleFunctionCalls.m to get started. Advantages: - supports reading v2 files - doesn t require the NI DLL, thus it doesn t require 32bit windows - supports interleaved data - allows only reading names & properties to get a quick feel for what is in the file - Since streaming files can get large (many GB), allows only retrieving subsets of data via keep or ignore flags Doesn t yet support: - big endian files Doesn t support: - files with DAQmx data - files with unsupported Matlab data types (extended float, etc) I haven t written very many wrappers to change the output data into more traditional formats. I d appreciate any submissions of wrappers that people make (like my TDMS_dataToGroupChanStruct_v1 & v2). Thanks! If the function doesn t work for you please let me know.

说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)

优点：1.对于信噪比高的信号滤波效果好； ％ 2.对于边沿的保护强过阈值滤波，不会产生阈值滤波情况下的过于平滑与Gibbs现象。 ％缺点：1.由于对边沿信号没做任何处理，所以边沿可能会有脉冲噪声保留下来； ％ 2.计算相关系数中，如果计算出来的小波系数点位置偏差大，则相关系数计算受影响； ％ 3.需要迭代运算，迭代的噪声能量阈值选取很重要，这里以开始段无信号处估计噪声； ％ 4.需要迭代运算，所以运算量比阈值法大； ％ 5.受分解层次影响，在大尺度上小波系数点位置偏差更大，相关系数计算不准确。 ％需要具体调整的地方：1.分解的尺度；()

说明：  光纤光栅的反射谱 包含两段代码 在MATLAB中仿真(the spectrum of fiber)

这是脉冲多谱勒雷达信号处理流程中的动目标显示的实现程序，采用的是脉冲对消法。(This is a pulse Doppler radar signal processing flow of the moving target indication of the realization of procedures, using the pulse cancellation method.)
