function Z=Rayfadsim（FdTsNs）
%------------------------------------------------------------------------------------
% This function can be used to generate multiple uncorrelated Rayleigh 
% channel fading waveforms with accurate second-order statistics compared
% with those of Clark‘s reference model.
%
%   Fd: maximum Doppler frequency 
%   Ts: sampling period
%   Ns: number of samples
%   Z: （1Ns） complex fading vector with unit variancei.e.R_{ZZ}（\tau）=J_0（2\pi Fd \tau）.
%  
%   Reference:
%   This simulator is built based on the following paper:
%   Yahong R.Zheng and Chengshan Xiao“Improved models for the generation of multiple
%   uncorrelated Rayleigh fading waveform“ IEEE communications Lettersvol.6June 2002
%
%   There are many ways to implement the 16 models provided by Zheng and Xiao.This one
%   is only an example and it is good for generating long sequence of the fading with
%   limited computer memory. Howeverthis example is not the most computationally efficient
%   one due to the “for-loop“ fact in Matlab.To remove the “for-loop“ will need more
%   computer memories.
