On the probability of appearance of primary user in IEEE 802.22 WRAN using an artificial neural network learning technique

Abstract

IEEE 802.22 wireless regional area networks promotes the use of TV white spaces to provide wireless broadband access to rural area using cognitive radio techniques. While selecting the best unused channel for transmission, a secondary user (SU) can use various parameters, among which the probability of appearance of the primary user (PU) in the channel.
