| Summary: | The cooperative detection in cognitive radio system was investigated based on multi-sensor data fusion. For a certain scale of the online users, an optimal user number participating in data fusion existed. Based on this fact, a measure-based fusion method was proposed. This method dynamically adjusted the user number in fusion according to the received signal in each detection activity. Simulation shows the performance of over 60% detection is improved by this fusion method than the method with fixed fusion user number. |
