水下无线信息-能量协同传输技术综述
Review of underwater simultaneous wireless information and power transfer technology
摘要
Abstract
With the rapid advancement of the Internet of underwater things(IoUT),underwater communication network nodes are confronted with severe dual bottlenecks characterized by"energy constraints"and"communication isolation".Underwater simultaneous wireless information and power transfer(U-SWIPT)technology,which achieves parallel trans-mission of energy and information by multiplexing the same physical field,is regarded as a key solution to these chal-lenges.Firstly,from the perspective of system architecture,the operational modes and trade-offs of four receiver mecha-nisms—time switching,power splitting,spatial switching,and frequency switching—were deeply analyzed.Secondly,based on the physical characteristics of transmission media,existing technologies were classified into three mainstream routes according to physical fields and were elaborated in detail:underwater electromagnetic-based,underwater optical-based,and underwater acoustic-based U-SWIPT technologies.Finally,based on the current research status,the appli-cable scenarios and technical challenges of different transmission technologies were analyzed.Ultimately,the future de-velopment trends of U-SWIPT technology are prospected,whereby theoretical support and technical references are pro-vided for the construction of underwater communication networks and the large-scale implementation of the IoUT.关键词
