Computation of Aggregate Interference from Multiple Secondary Transmitters

We describe how to compute the secondary system's generated aggregate interference in a shadow fading environment. We express the interference as an integral over secondary system's service area. For numerical computation of this integral we quantize its polar coordinate representation. We outline how the proposed numerical method can be used to compute the interference generated from a cellular network. For making this connection we parameterized the model by the cell size and the frequency reuse distance of the cellular secondary system.
