计算噪声图像的信噪比，matlab算法程序(Calculate the noise image signal to noise ratio, matlab algorithm program)

主要是matlab的画图，画的很好。很不错！应该可以看懂的。(The drawing is mainly matlab)

This is a code for comparison of 2-PAM, 4-PAM and 8-PAM. Generates a graph of each of the PAM on same figure, easily comparable. Code of 2,4 and 8-Pam included.

Taup域的反射法正演MATLAB程序，还不错，希望大家下去看看！(Taup domain reflectometry forward MATLAB program, well, I hope you go to see!)

Synthetic a time history to a target spectrum

异步电动机转差频率控制系统仿真，在matlab7.0下运行没任何问题，转速、磁链等参数都有显示，适合想要学习电机控制方针和矢量控制的。G1=35，G2=0.15，G3=0.0076，G4=2，G5=G6=9.55(Asynchronous motor slip frequency control system simulation, under the matlab7.0 running without any problems,, according to the parameters such as speed, flux has suited to want to learn motor control principle and vector control.)

广义互相关函数来确定两个信号的时延差，时延定位相关程序(Generalized cross-correlation function to determine the time delay difference between the two signals, the delay positioning procedures)

基于期望最大化的时变参数建模，时频分辨率高(Based on expectation maximization of time-varying parameter modeling, high time-frequency resolution)

用于生成FPGA中RAM所需要的初始化文件dds.mif,此文件生成的是余弦波形。(This document of .m can generate document of .mif to provide data for RAM of FPGA.)

本文简介了VC++和MATLAB特点，探讨了MATLAB与VC++接口编程的三种方法(This paper introduces the characteristics of VC++ and MATLAB to explore the MATLAB and VC++ programming interface, the three methods)
