在MATLAB下的一个对基带信号的采样变频至中频。GSM基站的接收频段为890～915 MHz。(A baseband signal sampling frequency to frequency under MATLAB. Receiving frequency band GSM base station is 890 ~ 915 MHz.)

本程序用matlab中的simulink对对象进行辨识，利用了S函数。(This procedure in simulink with matlab for object recognition, using the S function.)

program for emd and HHT

说明：  采用matlab编程求信号的hurst指数........(hurst parameter using matlab..........)

矩量法求解半波阵子天线的matlab程序，给出了方向图和增益还有输入阻抗，结果正确，程序规范，程序在实验报告中。(Moment Method time around half-wave antenna matlab procedures, given the pattern and gain and input impedance, the result is correct, procedural norms, procedures in the test report.)

说明：  初学微分方程数值解很实用的书籍，例子很详细，并附有程序。(Good book for student who wants to study tne numerical solution of differential equations)

显示采样率的GUI源码，包括理想采样，零阶保持采样，和其他一些方式。对于学习和理解采样定理很有帮助(Show the sampling rate of the GUI source code, including the ideal sampling, zero-order to keep sampling, and some other way. For learning and understanding of the sampling theorem helpful)
