项目摘要

Wireless communication and energy networks have enabled a plethora of novel applications in the last years. Both make use of the same and unique RF medium, but have been so far designed independently from each other. This visionary project conducted at Imperial College under the supervision of the PI Dr. Bruno Clerckx aims at challenging the current design by designing and proving the feasibility of a disruptive wireless network technology that wirelessly transfers energy jointly with information in wireless networks (shortly denoted as JWIET for Joint Wireless Information and Energy Transfer). The project will create a new paradigm shift in future capacity and energy efficient wireless communication and energy networks, by viewing them as a single network designed under a unified framework and by overcoming the energy constraint of wireless devices through the transfer of energy. Contrary to current wireless communication networks, interference is viewed as a source of energy that is to be harvested rather than mitigated. However, because interference in a wireless network influences dynamically the information rate and the amount of energy to harvest, finding the fundamental performance limits and effective interference management techniques is challenging and unexplored so far. In the last two years, Dr. Clerckx has successfully addressed this problem in a two-user and K-user narrowband MIMO interference channel and broadcast channels, under the assumption of an ideal energy harvester for which the RF-to-DC energy conversion efficiency is 100% irrespectively of the input waveforms.This project aims at extending and leveraging past achievements to solve the problem of JWIET in 1) wideband channels, and 2) in the presence of realistic RF energy harvesters accounting for actual RF circuitry and the fact that the RF-to-DC energy conversion efficiency of RF energy harvesters depends on the input waveforms.To put together this novel wireless network solution in a credible fashion, this project focuses on 1) identify theoretic rate-energy trade-offs for general wideband MIMO interference and broadcast channels accounting for realistic RF energy harvester models, 2) investigate the associated transmission strategies, 3) validate the feasibility of JWIET through experiment.The project and its experiment will be performed in partnership with National Instruments and Vodafone. The project demands an interdisciplinary study and it is to be conducted in a unique research group with strong track records in wireless communication, signal processing, numerical analysis, and JWIET. With the above and given the novelty and originality of the topic, the research outcomes will be of considerable value to design future wireless networks supplied by wireless energy transfer and give the industry a fresh and timely insight into the development of practical JWIET system, advancing UK's research profile of both RF energy transfer and communication in the world. Its success would change the broad ICT/Engineering landscape in developed but also emerging markets with applications in a large number of sectors, e.g. building automation, healthcare, telecommunications, smart grid, structural monitoring, consumer electronics, etc.

无线通信和能源网络在过去几年中催生了大量新颖的应用。两者都使用相同且独特的射频介质，但迄今为止都是相互独立设计的。这个富有远见的项目在 PI 博士 Bruno Clerckx 的监督下在帝国理工学院进行，旨在通过设计和证明一种颠覆性无线网络技术的可行性来挑战当前的设计，该技术可以在无线网络中与信息一起无线传输能量（简称为 JWIET，即联合无线信息和能量传输）。该项目将在未来容量和节能无线通信和能源网络方面创造新的范式转变，将它们视为在统一框架下设计的单一网络，并通过能量传输克服无线设备的能源限制。与当前的无线通信网络相反，干扰被视为需要收集而不是减轻的能量来源。然而，由于无线网络中的干扰会动态影响信息速率和要获取的能量量，因此找到基本性能限制和有效的干扰管理技术具有挑战性，并且迄今为止尚未探索。在过去两年中，Clerckx 博士在理想能量采集器的假设下，成功解决了两用户和 K 用户窄带 MIMO 干扰信道和广播信道中的这一问题，无论输入波形如何，射频到直流的能量转换效率均为 100%。该项目旨在扩展和利用过去的成果来解决 JWIET 在 1）宽带信道和 2）方面的问题。考虑到实际射频电路的真实射频能量采集器的存在，以及射频能量采集器的射频到直流能量转换效率取决于输入波形的事实。为了以可靠的方式组合这种新颖的无线网络解决方案，该项目的重点是 1) 确定一般宽带 MIMO 干扰和广播信道的理论速率-能量权衡，考虑到实际的射频能量采集器模型，2) 研究相关的传输策略， 3）通过实验验证JWIET的可行性。该项目及其实验将与National Instruments和Vodafone合作进行。该项目需要跨学科研究，并将由在无线通信、信号处理、数值分析和 JWIET 方面拥有丰富经验的独特研究小组进行。综上所述，考虑到该主题的新颖性和原创性，研究成果对于设计由无线能量传输提供的未来无线网络具有相当大的价值，并使业界对实用 JWIET 系统的开发有新鲜而及时的了解，从而提升英国在世界射频能量传输和通信方面的研究水平。它的成功将改变发达市场和新兴市场的广泛 ICT/工程格局，并在许多行业中得到应用，例如：楼宇自动化、医疗保健、电信、智能电网、结构监测、消费电子等。
