matlab书籍类的创建一章，有理多项式对象类型的构造、显示、运算符和函数重载等一些列程序代码(matlab class to create a chapter book, the construction of rational polynomial object type, display, operator and function overloading and some out code)

这个 matlab 代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线(Digital Unit Impulse Discrete Harmonic Signals and their Linear Combination Harmonic Signal with Exponential Envelope. Periodic Sequence of Rectangular Impulses Mixture of Harmonic Signal and White Gaussian)

vmd分解的源代码,程序带注释，易于理解(Vmd decomposition source code, program with comments, easy to understand)

说明：  图与网络学习，主要是与MATLAB结合的方法(Figure and learning, the main method of combining with MATLAB)

非常不错的QPSK在matlab中的仿真教程，文档中包含相关的所有代码！(Very good QPSK Simulation in matlab tutorial document contains all the code!)

大气波导环境下电波传播预测，基于抛物方程法模型的matlab程序；pe_tropos_ducting.m。(Wave propagation forecast in atmospheric ducting enviroments, based on the parabolic equation model matlab program:pe_tropos_ducting.m.)

It is the Simulated Annealing method coded by matlab and has a good results.
