  • Abstract
    In a centralised cooperative relay scenario, a dynamic time slot allocation scheme is proposed to maximise the system throughput of cognitive radio networks by considering variant channel capacities and users´ demands. Key parameters and propositions are verified theoretically with extended application cases and constraints, as a significant improvement on the traditional fixed scheme. Performance improvement has been verified by quantitative results.
