In this paper, we consider a scenario where multiple secondary users search for idle frequency bands in a spectrum consisting of multiple channels. The state of each channel is modeled as a discrete-time Markov process. In each time slot, one secondary user(SU) chooses one channel to sense and decides whether to use the channel based on the sensing result.(More)
In this paper, an approach is introduced to get complete rulebase fiom recorded data. At the beginning, a small number of fuzzy sets are defined on each variable to get a complete rulebase. In this case, even if there are missing rules, the rulebase can be completed by knowledge easily. Then, the number of fuzzy sets increased step by step until the(More)
