Cooperative Spectrum Detection Technology

摘要：

　　This paper mainly discusses the cooperative spectrum sensing technologies in cognitive radio system.First,the paper starts with the single-node signal detection,then categorizes the spectrum sensing technologies and covers the good and weak points of the three major methods.Second,it puts forward a cooperative spectrum detection model and focuses on the effect of the cooperative detection and cooperative communication on the spectrum sensing performance.Last,with the help of mixed cooperative detection model,this paper compares the speed and accuracy of the single-node spectrum detection and that of the cooperative spectrum detection.
