Abstract: In this paper, we provide a comprehensive analysis of aggregated interference by opprtunistic radios accessing the white spaces of the digital television taking into account the ¿hidden node¿ problem.We propose a new statistical interference model for cognitive network in the white space context based on the amplitude aggregate interference, which accounts for the parameters related to the sensing procedure, spatial reuse protocol employed by secondary users, and environment dependent conditions like channel fading and signal obstructions. We derive the characteristic function and the nth cumulant of the cognitive network interference on the DTV receiver. Moreover, the proposed framework can help to understand secondary network interference in the TV white space context for successful coexistence between the licensed system and opportunistic networks.
