Secondary user access based on stochastic link estimation in cognitive radio with fibre-connected distributed antennas

In this study, the authors consider the application of a system architecture called cognitive radio (CR) with fibre-connected distributed antennas in IEEE 802.22 wireless regional area networks (WRANs) as it could bring the benefits of much shorter wireless transmission distances, lower transmission...
