单负材料的透射谱分析，其中的设置了角度变化从0度到90度。可以发现透射频率随角度的变化规律。(Single-negative materials, the transmission spectrum analysis, which set the angle changed from 0 degrees to 90 degrees. Transmission frequencies can be found with the variation of the angle.)

matlab中的pn码仿真 PN码的仿真实验 pn码在通信系统中占据了重要的位置，在即将到来的3G通信中比较重要(the pn Matlab simulation code PN code simulation pn code in communications systems occupy an important location in the upcoming three G communications more important)

雷达系统仿真，模拟接收信号同噪声叠加过程(Simulate the operation in a radar communication system. Delay of the recieving signal and the noise addition is demonstrated.)

实现可见光通信的仿真，用OFDM的调制方式(VLC communication OFDM)

关于SAR成像的三种方法的matlab程序，可以看看，还不错(SAR imaging of the three methods on the matlab program, you can see, not bad)

this program helps you to perform signal modeling for AR, MA and ARMA signals

TSP simulated annealing matlab code

基于cvca模型的标准卡尔曼程序及误差分析，适用于学生(The standard model based on Kalman cvca procedures and error analysis, applies to students)

用数值方法实现该fsk信号的相关型解调器，完成一个二进制fsk通信系统的仿真(Numerical methods used in the implementation of the relevant type fsk signal demodulator, to complete a binary fsk communication system simulation)

由david vallado更新的轨道确定的程序代码，本程序融合sgp4和sdp4，包含193个文档(this procedure is the sgp4 prediction model from space command. this is an updated and combined version of sgp4 and sdp4)
