Aggregate Interference From WLAN in the TV White Space by Using Terrain-Based Channel Model
In this paper, the authors model the TV white space usage by a WLAN type secondary network. They derive a model that incorporates spatially non-uniform distributed user demand and terrain-based radio channel model. They follow the approach proposed by Electronic Communications Committee (ECC) and describe the interference from the pixels in the secondary area to the pixels in the TV coverage area. The demand is described by the household density and the radio channel is evaluated as attenuation between the pixels. They also study how well a Poisson Point Process (PPP) based interference model describes the actual interference. They modify the PPP model so that it can describe non-uniform user distribution and terrain-based channel model.
