基于能量获取的无线通信系统研究

Research on Energy Harvesting Communication System

由于部署便利及能提供无间断的绿色无污染的能量等特点,能量获取已经成为解决未来无线通信能耗问题的一项非常有潜力的技术。虽然能量获取技术仍存在能量来源不稳定、存储设备容量有限等限制条件,加之无线通信系统自身的信道与数据到达的随机特性,使得在无线通信系统中使用能量获取技术极富挑战性,但学术界与产业界在基于能量获取技术的无线通信研究中仍取得了显著进展。广泛调研了国内外在相关领域的研究现状及主要研究方向,考察了在基于能量获取技术的无线通信系统研究中的常用模型、系统框架与常用方法,对各研究方向进行了深入分析与梳理,最后对应用能量获取技术的无线通信系统的未来研究方向进行了总结和展望。

Energy harvesting （EH） is becoming a promising technology for future wireless communication network for its potential of saving nonrenewable energy and making the communication environmentally friendly. However, due to the unpredictable and intermittent nature of energy source, the capacity of storage devices, as well as the unpredictable nature of the communication channel and users＇ arriving data, the road to the communication system powered solely by harvested energy is plagued with potholes. Despite this, remarkable progress has been made in applying energy harvesting to wireless communications. An extensive survey on the current development status and main research fields was made, and the most common used model, system framework and optimization methods were analyzed carefully. Finally the future development for applying EH to communication systems was concluded.
