说明：  GSM信号的调制原理和生成的matlab仿真程序(GSM modulation signal generated by theory and simulation program matlab)

自适应（LMS）算法在噪声抑制中的应用。在仿真中，原始信号选为sin((0.2*pi)*t), 噪声信号采用标准白噪声，延迟D=1，收敛因子分别是u=0.001和u=0.3(Adaptive (LMS) algorithm in noise suppression application. In the simulation, the original signal is selected sin ((0.2* pi)* t), noise signal using the standard white noise, the delay D = 1, respectively, convergence factor u = 0.001 and u = 0.3)

说明：  本程序用matlab编写，给出了特定参数下，光纤掺杂深度与阈值之间的关系(pumping threshold vs adoping density)

2010 数学建模大赛 赛前matlab培训2(Lecture2 2010 Mathematical Contest in Modeling Training (matlab symbolic computation).zip)

说明：  品质因子(衰减的倒数)的计算程序，有井曲线作为输入可计算其地震波的衰减。(Quality factor (inverse of attenuation) of the computer program, a well calculated curve as the input attenuation of seismic waves.)

这是一个双馈感应电机的矢量控制仿真模型，用的是定子磁链定向(This is the vector control simulation model of doubly-fed induction motor with stator flux orientation)

绘制庞加莱图程序可做学习使用非线性动力学分析(Drawing a Poincare program can be used for learning Nonlinear Dynamics Analysis)

说明：  this is good code source for the main task in antenna study that is the optimization

STK 是卫星仿真工具包，由美国AGI开发的一款在航天工业领域中处于绝对领先地位的商品化分析软件。这里附上的是这个软件的教程。(STK is a satellite simulation tool kit developed by the United States AGI a field in the aerospace industry in the commercialization of the absolute leading position analysis software. Here attached is the software tutorial.)

BPSK 加上了（7,4）汉民编码，误比特率统计(BPSK with the (7,4) Han coding, bit error rate statistics)
