加窗函数，针对大家不知道如何加窗提出来的一个例子(an example of window function )

假设一个接收到的信号为：x(t)=s(t)+n(t), 其中s(t)=A*cos(wt+a), 已知信号的频率w=1KHz， 而信号的幅度和相位未知，n(t)是一个服从N(0,1)分布的白噪声。为了利用计算机对信号进行处理， 将信号按10KHz的频率进行采样。 通过对x(t)进行LMS自适应信号处理，从接收信号中滤出有用信号s(t). 在未知信号频率的情况下，通过对x(t)进行LMS自适应信号处理，从接收信号中滤出有用信号s(t). (Assuming a received signal: x (t) = s (t)+ n (t), one of s (t) = A* cos (wt+ a), the known frequency signal w = 1KHz, And the signal amplitude and phase of the unknown, n (t) is a subject to N (0,1) the distribution of white noise. The use of computers in order to deal with the signal, The signal by sampling frequency of 10KHz. Of x (t) for LMS adaptive signal processing, filtering from the received signal in the useful signal s (t). Frequency signals in unknown circumstances, the adoption of x (t) for LMS adaptive signal processing, filtering from the received signal in the useful signal s (t).)

本文使用三维FDTD算法实现文献《Application of the three_Dimensional Method to the analysis if Planar Microtrip Circuits》IEEE trans. On MTT 1990 38(7)的一个矩形微带贴片天线的S11参数的计算。采用MATLAB编程完成数值计算，并与文中的结果进行了比较。(This three-dimensional FDTD algorithm using the document " Application of the three_Dimensional Method to the analysis if Planar Microtrip Circuits" IEEE trans.
