Aggregate Interference in White Spaces
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.
