On the Probability, Rate, and Duration of Phase Outages in Nakagami Fading Channels

A plausible phase-envelope model has been recently proposed for Nakagami fading. In contrast to the usual assumption that the phase is uniform, the model leads to phase statistics that change according to the Nakagami fading parameter. Based on this model, we derive exact closed-form expressions for the probability, average rate, and average duration of phase outages in Nakagami fading channels. The new expressions reveal that the fading parameter has a deep impact on the Nakagami phase statistics.
