74汉明码的编解码和性能曲线,程序能够运行，且有注释(74 HAMMING CODES AND PERFORMANCE CURVES)

说明：  matlab实现的信道指标计算求误码率低的信道(Calculation of channel index realized by MATLAB to find the channel with low bit error rate)

UWB_Channel_IEEE_802_15_3a.rar是用MATLAB对UWB信道进行仿真的实例，所仿真的信道是UWB的标准信道模型。(UWB_Channel_IEEE_802_15_3a.rar is used for UWB channel MATLAB simulation examples, the channel simulation is the standard UWB channel model.)

使用cordic算法，基于verilog实现的atan功能，经过仿真验证，适宜工程使用。(ATAN,implemented with cordic.)

for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X Y Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies Please validate this function before using it

说明：  这是一篇讲述多雷达协同干扰策略和方法的论文，可参考进行相关研究。(This is a paper on the strategy and method of multi-radar cooperative jamming, which can be referred to for relevant research.)

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

温度报警系统程序，已经调试成功的，没有问题。(emperature alarm system program, has been successfully debugged, no problem.)

说明：  用MATLAB进行AM调制解调的仿真实验 包含包络 加噪 调制系数等变量的影响(The simulation experiment of AM modulation and demodulation with MATLAB includes the influence of envelope plus noise modulation coefficient and other variables)

BPSK调制在高斯信道下的性能，误比特率和信噪比的曲线(BPSK modulation performance under gaussian channel, signal to noise ratio and bit error rate curve )
