Cognitive radio spectrum sensing cooperative detection method

The invention discloses a cognitive radio spectrum sensing cooperative detection method, belonging to the technical field of wireless communication. The method disclosed by the invention introduces the fuzzy set knowledge into the distributed multi-user cognitive radio cooperative spectrum sensing, wherein the membership degree of the uncertain judgment statistic is obtained by a membership function on one hand, and on the other hand, the fuzzy measure and fuzzy integral are used for fusing the multi-cognitive user sensing results as a new fusing tool. The cognitive radio spectrum sensing cooperative detection method disclosed by the invention overcomes the shortcomings of the existing cooperative detection method and can obtain high detection performance.
