Hi,
can anyone please explain the next point -
Assume a flat fading Rayleigh channel, given by the relation
y = h*x + w %where h is a complex gaussian RV and w is noise
why does every textbook says E{|h|^2}=1 ??
where does this assumption comes from ? i mean, i understand the physical justification for the "Rayliness", because of the summation of many scatterers, none with dominant amplitude and so on, that gives according to law of large numbers to complex normal.
but why is the assumption that the mean power of the channel gain is usually 1 ?
