摘要: Cognitive Radio (CR) systems have been proposed to enable flexible use of the frequency spectrum in future generations wireless networks. These are expected detect bands that not actively used by licensed (primary) users and provide unlicensed (secondary) access these bands. In this context it is important for CR promptly react changes operating environment adapt changing patterns use. This motivates work presented paper, which studies adaptation detection threshold energy-based sensing dynamic scenarios under constraints imposed on probabilities missed false alarm.
