说明：  fira 实物小车的pid调节程序，效果很好，采用积分分离的pid控制器(fira-kind car' s pid adjustment procedures are very good, pid controller with integral separation)

矢量天线 求信号频率 求信号四个角度 仰角方位角 极化角仿真(Four angles of vector antenna demand signal frequency request signal)

用matlab对lenna图像进行处理，方法是自适应加权中值滤波，自己写的。(Lenna with matlab image processing of the method is adaptive weighted median filter, write your own.)

matlab命令大全，各种指令都有，有助于学习(matlab command Daquan, various instructions are conducive to learning)

This code consists of the frost filter coding.

matlab编写的m函数文件，输入为两个点得经纬度坐标，输出为A点相对于B点得方位角。(matlab write a function of m file, enter the latitude and longitude coordinates for two points was the output of A point relative to point B have azimuth.)

假设在一个ad hoc网络中，移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道，测量接收到的信号功率X，其中X= I + N, I为接收到的干扰，N是噪声。移动节点只有在X＜INThre时，才可以发射。式中，INThre为背景噪声门限。 在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10。 (Assuming in an ad hoc network, mobile node s transmission power is always constant PTX. To send data to the mobile node always monitor channel, measuring the received signal power X, which X = I+ N, I was received interference, N is the noise. Mobile node only when X <INThre when it is fired. Where, INThre threshold for background noise. In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )

基于DCT变换的图像压缩的基本原理及其实现步骤。采用DCT变换压缩的依据。图像压缩过程的最后步骤是编码量化了的图像。在此,我采用的是Huffman编码方法。并使用MATLAB7.0实现DCT图像压缩的仿真。(DCT based on the image compression)
