Abstract

In this paper, novel operating and backup channels allocation schemes for IEEE 802.22 system are introduced and their performances are investigated. Interference level and the probability of appearance for incumbent user are taken into account in order to optimally update the backup channels list. Additionally, the operating channel is allocated based on Carrier to Interference and Noise Ratio (CINR) so as to meet Quality of Service (QoS) requirement. Simulation results illustrate that performance is significantly enhanced by employing the proposed channel allocation schemes in the IEEE 802.22 system.
