rng and randn on matlab

Hi there,

Can we say this code has a good approximation about the channel coefficient for each SNR?

rng(1)

SNR=10:5:20;

N_frame=100000;

taps=4;

for i=1:length(SNR)

for 1:N_frame

chan_coef=sqrt(1/2)*(randn(1,taps)+1i*randn(1,taps));

...

end

end

My result showed that in one SNR condition, the chan_coef will be extremely small, but didn't appear in other SNR condition

Can you give more clarification on what results you are getting?
