在协作中继通信系统中,能量收集设备可从周围环境中收集能量,并将之用于支持中继设备工作,减少能源浪费和损害环境。文章首先对能量收集协作中继通信系统的系统模型进行了描述,其次针对其研究侧重点介绍了不同模型下的问题及解决方案,最后针对目前研究的不足提出了对下一步研究方向的展望。 In cooperative relay communications systems, energy harvesting devices collect energy from the surrounding environment and use it to support relay equipment operations, reducing energy waste and damaging the environment. The article first describes the system model of energy harvesting collaborative relay communication system, and then introduces the problems and solutions under different models for its research focus. Finally, it puts forward the prospect for the next research direction according to the current research deficiencies.
