分析了Tm，Ho共掺光纤激光器在达到稳态之前的动态弛豫振荡过程，形象描述了光纤激光器的动力学过程(Analysis of the Tm, Ho co-doped fiber laser prior to reaching the steady-state dynamics of relaxation oscillation process, the image describes the dynamic process of fiber lasers)

用于空间数据分析中的Kf计算，并坐车相应的图形(Spatial data analysis for the calculation of Kf, and the corresponding graphic car)

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

中国国旗部分程序，大家可以参考一下，希望大学学习MATLAB之用(this is a matlab program of the chinese flag,Please download carefully)

这是用Matlab写的m文件，实现图片灰度变换功能，具体功能和操作在程序中有详细说明(It is written with Matlab m file functions to achieve image gray-scale transformation, the specific functions and operations are detailed in the program)

说明：  GPS捕获的滑动相关捕获的算法的实现，包括C/A码的产生，数字化，还有精频的确定算法，很全的代码，希望对你有帮助(GPS captured captured sliding correlation algorithm, including the C/A code generation, digital, there are fine frequency identification algorithm, it is all the code, I hope to help you)

说明：  MATLAB-智能算法30个案例分析-终极版(带目录)(Matlab - intelligent algorithm 30 case analysis - Ultimate Version (with catalog))

matlab中的symerr函数可以求得误码率 只要看下文件中最后那个例子，这个函数你就会用了(matlab in symerr function as long as the error rate can be obtained see next document in this last example, this function you will use the)

总结了自己关于通信原理学习的一下认识,希望大家多交流(about Communication Fundamentals in my side)
