Abstract
Although unlicensed bands are used more and more, but licensed bands are not used enough. This brings challenges to the concepts of open spectrum and dynamic spectrum access. Dynamic spectrum access is an effective method of spectrum sharing, which can realize the effective utilization of spectrum resources. Cognitive radio technology can achieve effective utilization of wireless bandwidth. In this paper, the application of software radio technology in satellite network system is discussed. The problem of spectrum mobility and handover in cognitive satellite network system is studied. An efficient spectrum mobility and handover method for cognitive satellite network is proposed. The cross-layer handover protocol with minimum expected transmission time in cognitive satellite network system is studied, instead of maximum idle time of spectrum hole. performance analysis and simulation are carried out. The proposed spectrum mobility and handover scheme can reduce the expected transmission time and probability of spectrum mobility, and improve the overall performance of the system.
