1.2根发射天线、1根接收天线 2.最高信噪比为12dB，即仿真范围为0dB到12dB 3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真 4.每一帧数据为24个QPSK符号 综合仿真函数SimAlamouti(max_snr,max_err_symbol,symbol_per_frame) 具有一根接收天线系统的SER性能与二根接收天线的系统SER性能比较 SimAlamouti(12,20,24)">

说明：  直接使用摄像头检测人脸的程序，正确率还不是很准确(Directly face the camera detection procedure, the correct rate is not very accurate)

自行设计产生两个离散序列信号，对其进行相加、乘及卷积运算。 利用filter命令求下面LTI系统的冲激响应，画出系统的零极点图，判断系统的稳定性、因果性。 绘出系统的频响曲线 (To design of two discrete sequence of signals , their sum , multiplication and convolution . Seeking the following LTI system impulse response filter command , draw system pole-zero diagram to determine the stability of the system , causality . Mapping the frequency response curve )

Markov随机场的例子程序,对于初学MRF的人很有用,能得到直观的印象(Markov random sample program, for the beginner who MRF useful to get an intuitive impression)

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)
