自校正控制MATALAB源码,包括系统辨识，最小方差控制等内容( Matlab source code of STC)

在过零检测过程中，找过零点，并以此来进一步计算相位差等(In the zero-crossing detection to find the zero crossing, and to calculate the phase difference)

hopping code in digital communication systems

Mode locked lasers fiber code, I run it from appendix but its not working. Although I tried a lot to get it resolved. .m files are enclosed.

供做算法研究人员参考，表示出两帧图像间各个像素点的相对情况，包括最后计算压缩图像的峰值信噪比和压缩效果的源码。( Algorithm for researchers to do reference, Between two images showing the relative circumstances of each pixel, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.)

此程序用C语言用哈夫曼编码法实现了对英文的压缩与解压缩，是C语言编程一个比较经典的例子(this program in C language with Huffman coding method to achieve the right English compression and decompression, the C programming language is a classic example)

说明：  此为matlab的GUI绘图功能示例(This is the GUI graphics matlab example)

QPSK误码率仿真及星座图，仿真入门级。信号的调制译码(The Simulation and QPSK constellation, entry-level simulation. Decoding the signal modulation)

解决ode45问题的非常强大的软件，另一个是matcont，不过后者需要在matlab环境下运行(Very powerful software to solve the problem of ode45, another is the matcont, but the latter needs to run in matlab environment)
