用Matlab实现一个矩阵的循环码编码的仿真。(Implement a matrix with Matlab coding loop simulation.)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元数为10，快拍数为200，信噪比为20dB，阵元间距分别为 tambada/6 tambada/2、tambada。(Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element number 10, the number of snapshots for 200, SNR is 20dB, respectively array element spacing  tambada/6 tambada/2, tambada.)

黄金分割法，附带说明，程序可直接运行,,有实例说明，是数值最优化方面的(Golden section method, with instructions, the program can be run directly)

对2维doa进行估计，在不同的快拍数情况下，BPSK信号的经典MUSIC估计比单频信号的经典MUSIC估计方法均方根误差性能更好(On 2 d to estimate doa. In different fast take several cases, BPSK signal of classical MUSIC estimate than single frequency signal of the classical MUSIC estimation method root mean square error performance better. )

说明：  doppler 频移程序， 大家相互参考(doppler frequency shift procedures, U.S. cross-reference)

对最优波束形成准则中的最大信噪比，给出了其Matlab仿真源程序程序。(The optimal beamforming standards to the maximum signal-to-noise ratio, and gives the Matlab source program. )

这是简易的ASK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple the ASK signal modulation, the file into Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

不考虑压缩的REYNOLDS方程的求解简单程序(Not consider compression REYNOLDS equations simple procedure)

说明：  Lorenz 系统利用龙格库塔来用Matlab编程(Lorenz system using Runge-Kutta to use the Matlab programming)
