关于OFDM的基本原理和实现方案，以及相关的matlab仿真的源程序(On the basic principles of OFDM and the realization of the program, as well as the source matlab simulation)

有限差分正演模拟 声波 高阶 包含边界条件 震源方程(finite difference code with boundary condition and source function)

数值积分工具箱，Matlab大部分函数都放在了toolbox这个文件夹下面。可以试着把需要的函数和工具箱放进去看看能不能用。(Numerical integration toolbox, Matlab toolbox most functions are placed below this folder. Can try to put the toolbox needed to function and see if you can use.)

说明：  AWGN信道下高斯噪声干扰下GPS编码译码系统性能仿真，同时进行了误码率的仿真(AWGN channel Gaussian noise jamming GPS system performance codec simulation, at the same time the BER simulation)

matlab 编程艺术的源码，非常好非常好非常好非常好(matlab encode document)

提供了PID控制的几个MATLAB程序包括：增量式PID控制，PID极点配置控制，以及自校正PID控制。(Provides several MATLAB program of PID control includind: incremental PID control, PID pole placement control, and self-tuning PID control.)
