% Description: This m-file generates a Nr×Nt channel fading coefficients matrix
% Usage:  H=rayleighCH(Nr,Nt)
% Inputs:
%         Nr: the number of receiving antenna,either 1 or 2
%         Nt: the number of transmitting antenna
% Outputs:
%         H: rayleigh distributed channel matrix

function H=rayleighCH(Nr,Nt)
H=zeros(Nr,Nt);
R=eye(Nr*Nt);
X=randn(Nr*Nt,1)/sqrt(2)+j*randn(Nr*Nt,1)/sqrt(2);
H=reshape(R'*X,Nr,Nt);
