摘　　要：在认知无线电中,能量收集设备收集的能量,用来独立支持认知设备能量消耗,可提高认知设备的移动性,减少能源浪费和损害环境。文章首先对认知无线电中的能量收集理论框架进行描述,其次按照次级用户的工作模式将认知无线电中的能量收集系统分为同步工作模型和顺序工作模型,并介绍两个模型的研究成果,最后提出了存在的挑战和下一步研究方向。In the cognitive radio, the energy harvested by energy harvesting equipment ap- plied to independent support cognitive equipment energy consumption can improve cognitive de- vice mobility, and reduce energy dissipation and environmental damage. In this article, firstly the framework for energy harvesting theory in cognitive radio was described, and according to the secondary users working mode, the cognitive energy harvesting system in radio was divided into synchronous working model and the order model, and the research results of the two models were introduced. Finally, the existing challenge and the next research direction were put forward.
