说明：  此程序是应用型程序，主要应用于雷达阵列波束形成，应用较广(This procedure is applied procedure, mainly used in radar array beamforming application is more extensive)

二维信号卷积，若x为N1*M1的二维信号，y为N2*M2的二维信号，则卷积为(N1+N2-1)*(M1+M2-1)的信号(Two demension signal convolution. )

是由斯坦福大学的Andrea Goldsmith编著的关于无线通信的教材，很经典.(This book is writen by Andrea Goldsmith who is from Stanford University. It is a classic book for wireless communication.)

该程序主要对非球面镜进行波面拟合，首先读入采集的离散面型数据，可以是从椭圆曲面，抛物面等采样得到，也可以是通过其他软件计算得到的数据。然后将数据用Zernike多项式进行拟合得到非球面表达式各项的系数。(The program on the aspheric wavefront fitting, first read into a collection of discrete surface data can be Sampling from the oval surface, the paraboloid, can also be calculated data obtained by other software. However After aspherical expression obtained by fitting the data with Zernike polynomials coefficient.)

用matlab编的科斯塔斯环，希望有帮助(Costas loop using matlab helpful)

In recent years a substantial increase in the development of broadband wireless access technologies for evolving wireless Internet services and improved cellular systems has been observed [1]. Because of them, it is widely foreseen that in the future an enormous rise in traffic will be experienced for mobile and personal communications systems [2]. This is due to both an increased number of users and introduction of new high bit rate data services. This trend is observed for second-generation systems, and it will most certainly continue for third-generation systems. The rise in traffic will put a demand on both manufacturers and operators to provide sufficient capacity in the networks [3]. This becomes amajor challenging problem for the service providers to solve, since there exist certain negative factors in the radiation environment contributing to the limit in capacity
