Fade Statistics of Wireless Multi-User Systems

In this paper, we propose a new model named effective fade duration envelope to characterize the accumulative conditional fade durations of individual users or groups of users in wireless communication systems. The proposed model has the following novelties: (1) it introduces the statistical upper and lower bounds with the required degree of confidence for accumulative conditional fade durations during any given time interval; (2) it characterizes various conditional fading circumstances in wireless multi-user communication systems.
