In environments with non-uniform user density and correlated slow fading, the Poisson Point Process (PPP) model fails to capture the distribution of aggregate interference. One way to overcome this issue is to divide the deployment area into multiple disjoint clusters and describe the interference from each cluster using a PPP with cluster-specific PPP intensity and pathloss model. Obviously, too...
The estimation of the total interference generated from a secondary system is essential for protecting the primary receivers. However, interference level estimation from a large number of secondary transmitters is a challenging problem. In this paper, we estimate the aggregate interference as an integration over the power spatial density in the secondary system's deployment area. We modify such integration-based...
The main requirement for secondary operation over the TV white spaces is interference control. In this paper, we propose an interference control scheme that allows multiple secondary systems to maintain their aggregate interference at the TV receivers under specific protection limits. The main characteristic of the proposed scheme is the small signaling overhead required for the cooperation between...
