摘　　要：交会是认知无线网络中必不可少的操作,次级用户间通过交会完成通信链路的建立。盲交会策略中次级用户不需要网络集中控制者和公共控制信道来辅助,独立地完成交会。盲交会策略的设计借助于信道跳频技术避免主用户活动的影响,提高交会的性能。文章介绍了交会的基本概念、分类策略、系统模型和主要性能评价指标,详细介绍了基于信道跳频的盲交会策略。总结对比了最具代表性策略的性能,并对未来研究方向提出了展望。Rendezvous is an essential operation in cognitive radio networks, the secondary us- ers establish a communication link through rendezvous. The secondary user does not require net- work centralized controller and common control channel to assist in the blind rendezvous strate- gy, but completes rendezvous independently. Design for the blind rendezvous strategy based on channel hopping is to avoid affecting the primary users＇ activities and improve the performance. The basic concept, classification of rendezvous, system model and the main performance evalua- tion index were introduced, especially the blind rendezvous strategy based on channel hopping. The performance of the representative strategies were compared, and the future study direction was put forward.
