Abstract
Multipath propagation is one of the dominant environmental influences on the performance of wireless communication systems. Meanwhile, heavy-tailed interference from neighboring cells may further degrade communication quality in mobile systems. This paper employs notions of spatial diversity using an array of sensors to address the inter-signal coherence problem. At the same time, the paper proposes the use of fractional low-order moments to mitigate the effects of the heavy-tailed background noise environment. The improved performance achieved by the combination of these two processing modules is demonstrated via Monte Carlo simulations.File | Dimensione | Formato | |
