Cooperative Spectrum Sensing in Cognitive Radio Networks:A Survey

摘要：

　　Spectrum sensing technology plays an important role in cognitive radio which has been advanced as a technology to use frequency bands much more efficiently.Cooperative spectrum sensing is chosen to improve the performance of spectrum detection which can be limited by many factors, such as noise uncertainty, shadowing, and multipath fading effect.There have been many significant developments in the past few years on cooperative spectrum sensing.This paper surveys some methods about cooperative spectrum sensing in cognitive radio networks.
