convolving noise with noise will get Gaussian? what does that imply?

Here is something that other have not addressed (or so I thought) about the application of CLT in general. Couple of direct resultants of CLT include:- noise that you practically encounter in real systems is Gaussian. The fading that signal undergoes in wireless communications is Rayleigh (when line of sight (LOS) is not available) -KK
