Specifically, the novel closed-form expression for the outage probability (OP) of the cognitive network are derived. Furthermore, the asymptotic OP expression at high SNR is developed to reveal the diversity order and code gain of the considered network. Finally, simulation results are provided to demonstrate the validity of the theoretical results, and show the effect of antenna number and interfering satellite link on the performance of the cognitive network. © 2015 IEEE.(18 refs) Main heading: Satellite antennas Controlled terms: Antennas - Beamforming - Cognitive radio - Communication channels (information theory) - Relay control systems - Satellite links - Satellites - Signal to noise ratio Uncontrolled terms: Closed-form expression - Cognitive network - Decode and forward - Multi antennas - Outage performance - Outage probability - Relay network - Secondary sources Classification Code: 655.2Satellites - 655.2.1Communication Satellites - 711.2Electromagnetic Waves in Relation to Various Structures - 716Telecommunication; Radar, Radio and Television - 731.1Control Systems Database: Compendex |
