I want to generate coefficient h for Nakagami channel. But, when I use gamrand() function for that, I get values greater than 1.
In the eq. r(t) = hs(t) + n(t), I don't think h should be greater than 1. So what else do I have to do in order to generate h?

hi, for generating Rayleigh channel we can code as below:
h1=sqrt(0.5)*(randn+1i*randn)*(1/sqrt(2));%rayleigh channel
h2=sqrt(0.5)*(randn+1i*randn)*(1/sqrt(2));%rayleigh channel
h=[h1 0 0 0 0 h2];
for a 6 tap channel.
i don't know what the function "gamrand()" you just mentioned is?.but anyway i think you've d forget to normalize your coefficients.

Ok thanks. And sorry the function was gamrnd()

Hi, yup., it is correct for rayleigh fading. but for rician can you please write coefficient?
