Multi-Node Spectrum Sensing based on a novel Dempster-Shafer Theory
In this paper, a novel and efficient Dempster-Shafer (D-S) evidence theory multi-node spectrum sensing based on double threshold judgment is proposed. A specific coordinate operation of D-S theory and double threshold judgment is discussed. It defines the uncertain area in double threshold detection, controls the application range of D-S theory and obtains the final detection results by drawing a clear line between data decision and information fusion. A better performance and higher sensing efficiency in a low signal-to-noise ratio is resulted according to the simulations.
