Fading channel coefficient calculation

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?

[ponvignesh shanmugam]

 r(t) = hs(t) + n(t)  what does this mean? could you please explain

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()

Could you please tell me how to implement the above for weibull fading channel

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

[Akhil Singh]

Hey, do you know how to generate coefficient for rician fading ?
