| Abstract(in English) | This paper presents a cooperative sensing technique for the spectrum sharing between an existing system (primary system: PS) and a new wireless radio system (secondary system: SS) which equips the cognitive radio techniques. To enhance the detection performance, strategies of fusion of the local statistics from individual secondary users have been investigated. We define an effective weight, which depends on the received signal power from PS and noise power. A usage of the weight in cooperative sensing can improve the detection performance. We also propose the received signal power estimation method to determine the weight and analyze the statistics and mean square error of the estimator. Additionally, we design SS's parameters (number of samples, number of nodes, number of antennas, and length of estimation period) in multipath fading environment. The design criterion of each parameter is determined so that the detection performance in worst case can achieve required target detection performance for PS. |
