摘要 研究认知无线电网络(CRN)中CR用户机会式占用频谱的接入控制。阐明CR用户与授权用户合作接入控制策略,针对实际网络环境分析CR用户基于Markov模型和具有预测机制的透明接入控制策略。对于CR用户不同业务需求以及网络中存在的各种干扰,总结了基于功率控制的透明接入控制策略。提出基于CRN的接入控制进一步研究的关键问题。 Access control of Cognitive Radio Network（CRN） where Cognitive Radio Users（CRU） share spectrum access opportunities with licensed users is studied. The cooperative access control strategies are illustrated. The transparent access control strategies are focused on, which are based on respectively Markov model and prediction. Transparent strategies on the basis of power control are analyzed for the various service requirements and interference. Th.e key problems about the further research of the access control in CRN are proposed.
