说明：  covariance code for cr

overall snr estimation in signal

利用MATLAB编写，完成一定操作，并计时时间的实例。(Written using MATLAB, the completion of certain operations, and the timing instance of time.)

breaks up an array into a cell array of adjacent sub-arrays of equal sizes

火箭尾喷管的设计，主要包括动力计算，外形轮廓计算，温度计算及激波分布等。使用matlab编写(Rocket nozzle design)

MATLAB语言精要及动态仿真工具SIMULINK(Essentials of MATLAB language and SIMULINK dynamic simulation tool)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(Graduate study do not to upload copyrighted controversial content and Trojan code and agent software to access foreign sites)

用数组产生盲节点和信标节点，比循环产生好许多(Produce blind node and beacon node with arrays, produce much better than the cycle)

matlab仿真非相干信号宽带MUSIC方位估计，与DAS和MVDR方法进行对比。信号到达角度可调整(Incoherent broadband signal simulation matlab MUSIC DOA estimation, comparison with the DAS and MVDR methods. Signal reaches the angle adjustable)

this the matlab codes for detection of surveillance system and its working.and also there is motion detection codes in it
