Abstract

Cognitive radio is an advanced technology for more efficient spectrum utilization systems based on opportunistic spectrum sharing. The security-related issue is very important. This paper proposes that frequency hopping technology is introduced into the cognitive radio system in order to guarantee security. The design of frequency hopping pattern, which is the key issue for the cognitive radio system with frequency hopping technology, is illustrated. And the interference suppression performance of cognitive radio systems with frequency hopping technology is investigated. Performance analysis and simulation results verify the validity of the proposed method.
