摘要
电视空白空间(TV White Space, TVWS)是数字电视在数字切换(Digital switching, DSO)过程中为提高频谱效率而产生的一大部分UHF/VHF频段的空闲频谱。新推出的TVWS将提供新的通信服务。本文综述了电视空白空间认知接入的最新进展，包括组织内的监管发展和标准化进展，对电视空白空间不同认知接入机制的分析，以及TVWS频谱的潜在用例。
TV White Space (TVWS) is a large portion of vacant spectrum in UHF/VHF bands that are created during the Digital Switchover (DSO) for the higher spectrum efficiency of Digital TV. The newly available TVWS will enable new communication services. This paper presents the reviews on the state-of-the-art on cognitive access to TV White Space, including the regulatory development and standardization progress in organizations, analysis of different cognitive access mechanisms for TV White Space, and potential use cases of the TVWS spectrum.
