To model the processes that I need to examine the effects of diversity, I need to develop a fading simulator. My first stab is a pair of counter-rotating phasors (left-hand and right-hand). Each one would have a varying length and angular velocity. I could use the Rayleigh fading equation to set their magnitude. I am not sure about the angular velocities, are these constant or do they vary? If I resolve the two phasors as a vector sum, that would just give varying linear polarisation - which does not sound right.

There are lots of factors missing though. Does the angular velocity of a circularly polarised signal vary? How does the coupling between different linear polarisations work? And how does it work for circular polarisations? I suspect that the coupling between linear polarisations is a (Sin X)/X function (just the main lobe).
