M-PSK Recovery for Modem Design.

用Matlab编写的功率谱估计，输入数据是100年太阳黑子活动记录，用周期图法、最大熵值估计（AR法及Burg法），画出信号功率谱进而算出太阳黑子活动周期。(Matlab prepared using power spectrum estimation, input data is 100-year record of sunspot activity, using periodogram method, the estimated value of maximum entropy (AR Law and Burg method), draw the signal power spectrum and then calculate the sunspot activity cycle.)

正弦信号的谱分析及提取 是一个课程设计的题目 程序能够运行 (Sinusoidal signal spectral analysis and extraction is the subject of a course design programs to run)

说明：  MATLAB工具箱进行线性回归、多元线性回归、非线性回归的很好的例子，附有教程PPT以及MATLAB程序，很实用，欢迎大家下载。(MATLAB toolbox linear regression, multiple linear regression, nonlinear regression of a good example of PPT, as well as MATLAB program with tutorials, very useful, welcome to download.)

LTE HARQ Presentation Draft

Matlab5参考书 1.介绍主要的模块和大体的功能 2.一些函数的详细信息(MatLab5 reference book 1.introduce the mainly models and the general functions 2.details of some functions)

这是一种搜索有向圈的算法，广泛被用于图论中，非常地实用(There is a search algorithm to the circle, is widely used in graph theory, very useful)

Matlab/simulink环境下开发的，基于平均值理论的发动机动力学模型，适用于发动机或整车控制策略开发使用。(Developed under the Matlab/Simulink environment, based on the average of the theory of engine dynamic model, suitable for the engine or vehicle control strategy developed using.)

里查得森(Richardson)法解偏微分方程的程序。解的是定步长的抛物型偏微分方程： du/dx - a * d2u/dx2 = 0 在程序中可以更改 a 的值以实现不同系数的解。由于它是一种显式格式，解的结果不稳定 在Matlab7下面运行发现竟然有一些值达到十的几十次方,这是算法本身决定的。不是程序有错误(Richard Anderson (Richardson) Solving partial differential equations procedures. Solution is scheduled to step parabolic partial differential equation: du/dx- a* d2u/dx2 = 0 in the procedure can be changed in order to realize the value of a different coefficient of the solution. Because it is an explicit format, the result of instability in the solution of the following Matlab7 running even found some value reached ten dozens of parties, this is the decision algorithm itself. Not a procedural error)
