摘要: We propose a multi-layer spectrum sensing optimisation algorithm to maximise efficiency by computing the optimal and transmission durations for fast changing, dynamic primary user. Dynamic user traffic is modelled as random process, where changes states during both period reflect more realistic scenario. Furthermore, we formulate joint constraints correctly interference lost opportunity of secondary period. Finally, implement novel duty cycle based detector that optimised with respect PU accurately detect activity Simulation results show unlike currently used detection models, proposed can jointly optimise simultaneously satisfy considered traffic.
