Communication related programs are really important to understand the working of the systems.

说明：  K分布高斯杂波仿真，matlab，网格映像法(Gaussian K distribution clutter simulation, matlab, mesh imaging method)

声音反射的实现，文档里附有运行的图样，即声音反射的波形(voice reflected the realization documentation is enclosed operation of the drawings, that is reflective of the voice waveform)

x0 = ones(2,2) Make a starting guess at the solution options = optimset( Display , off ) Turn off Display [x,Fval,exitflag] = fsolve(@myfun,x0,options) The solution is x = -0.1291 0.8602 1.2903 1.1612 Fval = 1.0e-009 * -0.1619 0.0776 0.1161 -0.0469 exitflag = 1 and the residual is close to zero. sum(sum(Fval.*Fval)) ans = 4.7915e-020

AR模型参数确定后计算出功率谱, 用Levision_Durbin 算法(AR model parameters were calculated to determine the power spectrum, using Levision_Durbin algorithm)

此程序是matlab中给出矩阵均值的程序，注释详尽，使用简单，其中的注释详细，自己可以对变量做相应的变换(This procedure is given in matlab matrix mean the procedures, the Notes detailed, easy to use, which notes in detail that they can make the corresponding change of variables)

Transfer functions between interfaces can be easily calculated by division of the total (=upward+downward) displacement response on the corresponding interfaces.
