Cognitive radio (CR) is considered as a key enabling technology for dynamic spectrum access to improve spectrum efficiency. Although the CR concept was invented with the core idea of realizing "cognition", the research on measuring CR cognition capabilities and intelligence is largely open. Deriving the intelligence capabilities of CR not only can lead to the development of new CR technologies,...
An important challenge regarding peer's trust valuation in peer-to-peer (P2P) networks is how to cope with such problems as dishonest feedbacks from malicious peers, collusions and complex strategic frauds, which cannot be effectively tackled by the existing solutions. Thus, a reputation-based distributed trust management model for P2P networks, named RATM for short, is proposed to quantify and evaluate...
An important challenge regarding peer's trust valuation in peer-to-peer (P2P) networks is how to cope with such problems as dishonest feedbacks of malicious peers and attacks from strategic malicious peers, which cannot be effectively tackled by the existing solutions. So a feedback confidence (FC)-based distributed trust management model for P2P networks, named FCTM for short, is proposed to quantify...
This paper presents a new approach for blind equalization of communication systems with channel coding. Based on the Channel Independent Viterbi Algorithm (CIVA), the new method performs blind sequence detections applying the information of channel coding. Specifically, the trellis searching can be simplified by considering the linear block channel encoder. The joint CIVA-based detector/decoder not...
