Abstract

The digital switchover plan in the UK, expected to be completed in 2012, is capable of freeing up a total of about 240MHz TV bandwidth. This includes the license-exempt access to TV White Spaces (TVWS) as defined in IEEE 802.22 standards for Wireless Regional Area Network (WRAN). In this paper, a simulation model based on the existing keep-away region algorithm is established and verified to explore the potential TVWS resources with the Cognitive Radio technology at any given location in the UK. The proposed power control algorithm based on the maximum allowed transmission power is to replace the keep-away region algorithm and improve the availability of a cognitive radio (CR) operation. Finally, a comparison between these two algorithms is made in terms of system capacity.
