rice_fading.m

用matlab的simulink做的对选择式分集进行的测试 及性能验证。

function r1 = rice_fading(in)
Kdb=-inf;
N=1;
Mi=1;
K = 10^(Kdb/10); 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,Mi*length(r)); ki = 1;
for i=1:length(r)
rt(ki:i*Mi) = r(i); ki = ki+Mi;
end
r = rt;
r1=in.*r';
