赖斯衰落信道仿真

%With this MATLAB code one can obtain both
% the “symbol-level” and “block-level” Rician fading 
%channels for a pro-per chosen interpolation factor Mi. 
%Also, Rayleigh fading samples can be obtained for Kdb = -inf. 
%

function r=rician_fading(Kdb,N,Ni)
K=10^(Kdb/10); %赖斯因子
const=1/(2*(K+1));
x=randn(1,N); y=randn(1,N);
r=sqrt(const*((x+sqrt(2*K)).^2+y.^2)); rt=zeros(1,Ni*length(r)); ki=1;
for i=1:length(r) 
    rt(ki:i*Ni)=r(i);ki=ki+Ni;
