Abstract :
This paper derives equations that describe level-crossing rates and average fade durations for mobile receivers operating in spatially complicated multipath channels. The results are useful for describing fading statistics for wireless systems that operate in realistic propagation channels or employ smart antennas, adaptive arrays, or other technologies that lead to a non-omnidirectional distribution of multipath power in space
