On the simulation and correlation properties of phase-envelope Nakagami fading processes

We propose a general method for simulating both envelope and phase of Nakagami fading channels, allowing for arbitrary values of fading parameter and anisotropic scenarios. The method complies with the newly-derived Nakagami phaseenvelope distribution and Nakagami envelope autocorrelation. Relying on the proposed scheme, we also derive precise closedform approximations to the envelope, phase, and quadrature component autocorrelations and to the quadrature component crosscorrelation.
