给出卫星适当的初始位置和速度，利用其运动微分方程，求出2－3个周期内的轨道，并画出机械能和动量矩的大小随时间变化的曲线。(Given appropriate initial satellite position and velocity, using the equations of motion, find the 2-3 cycle track, and draw mechanical energy and angular momentum of the size of the curve over time.)

这是 Robocup2d仿真足球UVA底层中最重要的也是最基础deMeer5的详细决策分析，对于刚刚接触Robocup的学员来说非常不错，强烈推荐！！(This is Robocup2d simulation UVA football is the most important is the underlying basis for deMeer5 most detailed decision analysis, for students just touch Robocup is very good, highly recommended! !)

Simulates BER of BFSK in AWGN channel

接收来自下位机的数据,然后进行数据处理和通讯(From under the machine to receive data bit, and then data processing and communications)

CDMA二代移动通信的Matlab仿真程序段，运行良好。(CDMA second-generation mobile communication segment of the Matlab simulation program, run well.)

DTX matlab code for g729 annect B

frequency expander. Matlab code for expander.When x is a vector, this function adds L-1 after each element of x. When x is a matrix, each column of it treated as vector and expanded L fold. SQUARE-ROOT RAISED-COSINE PULSE: h=sr_cos_p(N,L,alpha) This function generates a square-root raised-cosine pulse of length N+1. There are L samples per symbol period. alpha is the roll-off factor.

地震数字处理的基本程序，其中包括滤波褶积，fft，dft，自相关互相关，以及偏移等，对地质学人员比较有用(Digital processing seismic basic procedures, including convolution filter, fft, dft, autocorrelation cross correlation, and offset, etc., more useful for people geology)

UWB1000模块测试所得数据初步处理之后，已知锚点的坐标，可利用该文件里的程序解算标签三维位置。(After preliminary processing of data obtained from UWB1000 module test, the coordinates of anchor points are known, and the program in this file can be used to calculate the three-dimensional position of tags.)

对原始灰度图像进行图像压缩，对此图进行 8×8 DCT 变换后，分别只保留 DC系数，以及保留前 4、8、16 个变换系数(DC＋AC) ，然后再分别进行 IDCT 变换 (The original gray image compression, this map for 8 × 8 DCT transform, respectively, to retain only the DC coefficient, and to retain the former 4,8,16 months transform coefficients (DC+ AC), and then separately IDCT transform)
