1) The last time I checked the code, I arrived at the same conclusion. 2) Its just a name for a complex number in which the real and imaginary parts are taken from a gaussian distribution. I think it comes from the fact that a 2D gaussian random vector radius has Rayleigh distribution.
You didn't asked, but just in case you find this in the future: the relation between the N_0 parameter of a continuum white noise model and the SNR (or variance) of its discrete counterpart is not trivial. 2015-07-25 20:38 GMT-03:00 Richard Bell <[email protected]>: > I'm trying to figure out how to convert the channel model noise voltage > value into an SNR value for a simulation I'm making.
