Abstract(in English) | In cognitive radio networks, it is important for secondary users (SUs) to accurately sense wireless channels for primary users (PUs). To improve the detection performance, cooperative spectrum sensing is proposed, in which SUs form distinct groups and the SUs in a group share the same sensing result. Parameters such as the miss-detection rate and false-alarm one of each SU are required to form appropriate groups, however, most of previous studies treat these parameters as known. In this paper, we consider an automatically learning technique for the optimal group formation without a priori information of the miss-detection and false-alarm rates. We formulate this problem as a multi-armed bandit problem, developing a repeated group formation scheme with which an exploration-exploitation tradeoff is taken into consideration. We investigate the performance of the proposed scheme by simulation. |
