Matlab FFT 实现 时域频域转换

本程序为利用给定节点，求未知节点插值法，包括拉格朗日插值法和牛顿向前插值法(This procedure for the use of a given node, seeking the unknown node interpolation method, including the Lagrange interpolation method and Newton' s forward interpolation)

无线通信系统中,信道间的相关性随着天线数目的增加而减小,当趋于无穷时,可视为正交.此为这一观点的仿真程序.(In wireless communication system, the correlation between channel and decreased as the number of antennas, when becomes infinite, can be treated as orthogonal. This a simulation program for this view.)
