Comparison of propagation models with real measurement around Hull, UK

Cognitive Radio has now become a realistic option for the solution of the spectrum scarcity problem in wireless communication. TV channels (primary user) can be protected by accurate prediction of TV White Spaces (TVWS) by using propagation models. Knowledge of radio propagation is considered essential in any wireless network, with dependence on appropriate deployment and management strategies leading to a suitable design for each network. In this paper, we investigate the best empirical propagation model for predicting TVWS by examining the performance of three propagation models (Extended-Hata, Davidson-Hata and Egli) in the TV band 470 to 790MHz when compared with a comprehensive set of propagation measurements taken in randomly-selected locations around Hull, UK.
