h is a mutipath channel, as depicted in the following picture.
a_i is the channel gain. tao_i is the channel delay.
a_i and tao_i are i.i.d random variables respectively. It could be reinterpreted in the form of h = X + j*Y.
In the following picture, X is the real part, and Y is the imaginary part.
What I fall to understand is why is X and Y are independent from each other?
It seems to me they both consists of the same two random variables.
My friends suggest they're irrelavant and orthogonal, which I still couldn't know how?
