Cooperative Spectrum Sensing Technique

2007 International Conference on Wireless Communications, Networking and Mobile Computing, 2007
Cognitive Radios (CRs), which sense the spectrum and implement opportunistic sharing when no licensed user is found to use it, are able to improve the efficiency of spectrum. Spectrum sensing must be firstly solved in CRs. Cooperative sensing can make good use of network resources, obtain higher gain and make the network steadier. In this paper we give

Sensor Selection for Cooperative Spectrum Sensing

2008 3rd IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks, 2008
This article considers spectrum-on-demand in a cellular system. A communication system that wants to access spectrum to which it does not own a license must perform spectrum sensing to identify spectrum opportunities, and to guarantee that it does not cause unacceptable interference to the license owner.

Sensing Confidence Level-Based Cooperative Spectrum Sensing Algorithm

Applied Mechanics and Materials, 2012
Cooperative spectrum sensing is a key technology to tackle the challenges such as fading or hidden terminal problem in local spectrum sensing of cognitive radio system. Conventional cooperative method can improve the detection performance in some sense, but increase overhead of control channel.
