摘　　要：认知无线系统中谱感知是基础与前提,以认知无线系统谱感知的研究为主题,在综合相关研究成果的基础上从谱感知研究的核心技术内容入手,着重对有关本地检测的技术手段、先验知识的参考应用、谱预测与主用户网络信息的利用等关键性问题进行了阐述分析,对涉及问题解决的核心要点进行了概括分析,同时在综合考虑认知无线系统工作应用实际的情况下,对今后认知无线系统谱感知研究需要重点关注的方向进行了讨论分析。For cognitive radio system, spectrum sensing is the basis and premise. The paper takes the study of the spectrum sens- ing as the subject. Starting with the study of the key technology of the spectrum sensing, the paper, based on consulting and analyzing the current research results in spectrum sensing, analyzes the local spectrum sensing technology, the consulting use of the prior information about the primary user, spectrum sensing forecasting and the use of the primary network information. And at the same time, the paper gives a summary analysis on the solving of the key point of the spectrum sensing problem. Then, with consideration of the common operation and the system use, the paper makes some discussions on the important research directions needed for cognitive radio spectrum sensing in the future.
