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.
