Cooperative Diversity of Spectrum Sensing for Cognitive Radio Systems

Dongliang Duan, Liuqing Yang, Jose C. Principe
2010 IEEE Transactions on Signal Processing  
Hence, we consider both false alarm and missed detection probabilities individually and jointly via the average error probability.  ...  We first notice that, in a spectrum sensing problem, diversity should reflect both the false alarm and missed detection behaviors since they respectively capture the efficiency and reliability of the overall  ...  and the missed detection diversity.  ...

Local and Global Information Exchange for Enhancing Object Detection and Tracking

Jinseok Lee
2012 KSII Transactions on Internet and Information Systems  
Local and global information exchange allows a missed local object's position to recover.  ...  However, the exchange of the information may degrade the detection and tracking performance by incorrectly recovering the local object position, which propagated by false object detection.  ...  Given the local information detected, our proposed combination system exchanged the local and global information between the two cameras, which corrected the missing and false detection, as shown in Fig  ...

Optimal Hard Decision Fusion Rule for Centralized and Decentralized Cooperative Spectrum Sensing in Cognitive Radio Networks

Ashish Rauniyar, Jae Min Jang, Soo Young Shin

Performance of deterministic local sensing aggregation under interference

Amin Nahvi, Viktoria Fodor, Ioannis Glaropoulos
2010 Proceedings of the 5th International ICST Conference on Cognitive Radio Oriented Wireless Networks and Communications  
This loss however affects mainly transmissions with less significant information, and therefore low delay aggregation with efficient spatial time division multiplexing is possible.  ...  We propose a time division multiple access protocol to exchange sensing information among neighboring sensors, that is tunable in terms of sensing cooperation range and frequency reuse distance.  ...  The interference depends on the probability that a primary signal is not detected, called missed detection, and the reaction time of the WSN, including the sensing time and the time for sensing information  ...
