Rayleigh fading question

[lincolndsp]

Rayleigh can be generated by
R=randn(N,1)+sqrt(-1)*randn(N,1); and the envelope is distruibuted according to rayleigh as r=abs(R)

I'd like to ask if these formulas are true for slow flat fading
and is the phase of R uniformly distributed in [0,2pi]?

Dont know if slow fading can be modelled by rayleigh

>and is the phase of R uniformly distributed in [0,2pi]?

Yes, The arctan of the ratio of two independent Guassian random variables is a uniformly distributed in [0, 2pi], even though dont know how to prove it.
