Abstract [en]

Using frequency hopping for fair resources allocationin TV white spaces is proposed and evaluated in this paper.The degree of fairness is judged by the achieved throughputby different secondary users. The throughput of the secondaryusers is determined by their permissible transmission power andthe interference from the TV and other secondary users. Thepermissible transmission power for secondary users in TV whitespaces in different channels is investigated. The main concern ofcalculating the permissible secondary user transmission power isprotecting the primary TV receivers from harmful interference.With the aid of SPLAT (RF Signal Propagation, Loss, AndTerrain analysis tool), the received TV signal power in a studycase of the surroundings of the city of G¨avle is fetched. Theinterference from the TV transmission into the free channels ismeasured in six different locations. The simulated system is adeployed Wi-Fi access points in a building representing an officeenvironment in an urban area. Moreover, the size of the hoppingset and the number of APs influences are investigated.
