GA-VRP-MATLAB

Introduction to matlab tutorial with matlab codes for example to guide the readers

说明：  这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。(main_STBC_MIMO_OFDM.m)

这是一个matlab的初学者的小算例，非常适合于初学者学习(This is a beginner' s small matlab example is very suitable for beginners to learn)

简单的仿真过程，通过输入信号，和s函数可以得到一定的仿真结果(Simple simulation process, the input signal, and s functions can get some simulation results)

分数阶PID仿真程序，用D分割法求取分数阶PID稳定域(Fractional PID simulation program, to obtain the order stability region of PID fraction with D segmentation method)

对QPSK解调系统完美建模，其中通过改变码元速率和载波频率，再计算相应的环路滤波器的参数，即可实现多种QPSK模型的解调，且该模型可通过SYSTEM generator进行量化，从而生成ISE能直接使用的HDL代码。 matlab版本：2007a(Perfect for QPSK demodulation system modeling, which by changing the symbol rate and carrier frequency, and then calculate the corresponding parameters of the loop filter, QPSK demodulator can achieve a variety of models, and the model can be quantified by SYSTEM generator thereby generating ISE HDL code can be used directly. matlab version: 2007a)

说明：   数值计算 matlab 单模光纤一维模场分布(Numerical matlab one-dimensional single-mode fiber mode field distribution)
