The η-μ Joint Phase-Envelope Distribution

This paper derives a simple and closed-form expression for the phase-envelope joint distribution of the η-μ distribution, a general fading model that includes the Hoyt and the Nakagami-m models as special cases. In the same way, the marginal distribution of the phase is also obtained. These analytical expressions reduce in an exact manner to those of the particular cases comprised by the η-μ distribution. Some plots illustrate the behavior of the phase for several fading conditions.
