Cognitive wireless networks usually utilize large numbers of cognitive nodes to collect cognitive information of the authorized frequency bands and do automatic configuration to finish spectrum sharing processes. How to realize joint detection and choose appropriate cognitive nodes to achieve opportunity type spectrum access should be considered in a cognitive wireless communication system. In this paper, the authors present a joint detection algorithm to finish cognitive information collection and one user selection scheme to minimize co-channel interference for the downlink of a cognitive mesh network with the coexistence of many primary nodes and cognitive nodes.
