说明：  MATLAB关于遗传算法的几个经典实例，需要的就下吧(MATLAB Genetic Algorithm on a few classic examples of needs on the next bar)

gps信号的跟踪环程序 可以实现最基本的载波环跟踪功能(gps signal tracking loop program can achieve the most basic function of the carrier tracking loop)

This code consists of the frost filter coding.

matlab 实用教程（ppt，源代码） 包括画图 计算 变成(matlab Practical Guide (ppt, source code), including the calculation into a drawing)

LDPC encoding and decoding for an AWGN channel

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度

这个程序基于matlab，用经典的算法用于求解方腔流问题(This program is based on MATLAB classic algorithm for solving the cavity flow problem)

该程序的优点在于障碍可以自己设置，也可以读图。(The advantage of this program is that obstacles can be set by themselves or read pictures.)

关于晶闸管控制串联电容器对系统暂态稳定性影响的matlab仿真。(Moeling and simulation of transience stability on a thyristor controlled series compensation. More comprehensive mathematical equations of TCSC circuit for any period (including the whole transient processfrom firing the thyristors to a steady state) and for the steady state relating to the voltages and currents of the capacitor,inductor and thyristor components are precisely developed by using Laplace transformation. And the accurate mathematicalrelationship between the fundamental impedance of TCSC and the firing angle of the thyristors is further derived by using Fourier analysis. Via the simulation, having a good understanding of the transience stability on a thyristor controlled series compensation. )
