Exercise about modelling and identification system

functions of a circular array

仿真计算电磁波在两种介质表面的反射系数和折射系数。(Simulate the reflect coefficient and the transport coefficient of an EM wave when it meets a border of two different media.)

在时域中表示，短时傅里叶变换，取1000个采样点，加窗函数，画出原始信号，三维，等高图(In the time domain, said the short-time Fourier transform, take 1000 a sampling point, add window function, draw the original signal, 3 d, contour map)

rake接收机仿真，Rake接收机是一种能分离多径信号并有效合并多径信号能量的最终接收机。瑞克接收的过程相当于用一个钉耙将各个多径信号“耙”出来，然后加以收集。(rake receiver simulation, Rake receiver is a multipath signals can be separated and the effective integration of multi-path signal energy of the final receiver. Rick received the equivalent of using a rake to process each multipath signal " rake" out, and then collecting them.)

说明：  用matlab画电场,MATLAB与FDTD联合仿真，绘制出电场磁场电流分布图(Matlab to draw the electric field)
