Big natural or manmade disasters damage infrastructure and cause severe effect on civilizations. Existing telecommunication infrastructure goes down as well as power, water etc. Quick and effective rescue operation requires a collaborative communication infrastructure for the rescue teams. Emergency spectrum usage of the rescue teams is one of the major issues in such scenario. Different teams interfere...
Spectrum sensing is a key technical challenge for the cognitive radio (CR) technology which allows it to access the spectrum of the licensed systems without causing interference to them. It is well known that cyclostationarity detectors have a great advantage of the robustness of noise uncertainty which significantly degrades the performance and makes its implementation difficult in energy detectors...
As a growing interest in the cognitive radio technology has been taken based on the idea of opportunistic spectrum use, the spectrum sensing technique for dynamic channel environment is more and more important to ensure that cognitive radios would not interfere with primary systems while it achieves reasonable throughput opportunistically. Architecture based on filter bank allows to sense multi-channels...
