项目摘要

In recent years there has been a huge explosion in the use of mobile devices such as smartphones, laptop computers and tablets which require a wireless connection to the internet. Numbers are forecast to reach 40 billion worldwide by 2020 as areas as diverse as the home, transport, healthcare, military and infrastructure experience increasing levels of embedded 'smart' functionality and user operability. Major applications such as future 5G communications systems, the Internet of Things and Autonomous Vehicles are driving this technology. At present wireless systems operate at frequencies up to 6GHz. However, there is a growing realisation that the spectrum below 6GHz cannot support the huge data rates being demanded by future users and applications.The next step is to develop technologies utilising much higher frequencies to give data rates compatible with future demand. Currently, world licencing bodies such as ETSI and ITU have identified millimetre wave frequencies up to 90 GHz as most likely for this expansion in the spectrum. Strategically, the UK must develop wireless technologies to compete on the world stage and increase its competitiveness particularly in competition with the Far East. Superfast 5G level Telecoms infrastructure is central to the Industrial Strategy Green Paper, which the UK government has been championing and highlighting in the ten pillars of combined strategy. Two technology bottlenecks in millimetre wave receivers, which are important aspects of future communication systems, are: 1) current receiver architectures are unable to directly digitise millimetre wave signals with acceptable power consumption, and 2) antenna arrays are not sufficiently frequency agile. This project aims to address both bottlenecks using new techniques developed on the FARAD project. The proposed research will embrace the co-design of antennas, filters and amplifiers with track-and-hold-amplifiers, analogue-to-digital-convertors and digital down conversion. This will result in new receiver architectures for fully digital massive MIMO systems. The techniques and architectures developed in this project will enable future high-frequency networks to operate efficiently in the new millimetre wave transmission bands. The research will have far-reaching consequences for solving the wireless capacity bottleneck over the next 20 to 30 years and keeping the UK at the forefront of millimetre wave technology and innovation.

近年来，智能手机、笔记本电脑和平板电脑等移动设备的使用出现了巨大的爆炸式增长，这些设备需要无线连接到互联网。预计到 2020 年，全球这一数字将达到 400 亿，因为家庭、交通、医疗保健、军事和基础设施等不同领域的嵌入式“智能”功能和用户可操作性水平不断提高。未来 5G 通信系统、物联网和自动驾驶汽车等主要应用正在推动这项技术的发展。目前无线系统的运行频率高达 6GHz。然而，人们越来越认识到，6GHz 以下的频谱无法支持未来用户和应用所需的巨大数据速率。下一步是开发利用更高频率的技术，以提供与未来需求兼容的数据速率。目前，ETSI 和 ITU 等世界许可机构已确定高达 90 GHz 的毫米波频率最有可能用于频谱扩展。从战略上讲，英国必须发展无线技术以在世界舞台上竞争，并提高其竞争力，特别是在与远东的竞争中。超高速 5G 级电信基础设施是产业战略绿皮书的核心，英国政府一直在联合战略的十大支柱中倡导和强调这一点。毫米波接收器是未来通信系统的重要方面，其面临的两个技术瓶颈是：1）当前接收器架构无法以可接受的功耗直接数字化毫米波信号，2）天线阵列频率不够灵活。该项目旨在利用 FARAD 项目开发的新技术解决这两个瓶颈。拟议的研究将包括天线、滤波器和放大器与跟踪保持放大器、模数转换器和数字下变频的协同设计。这将为全数字大规模 MIMO 系统带来新的接收器架构。该项目开发的技术和架构将使未来的高频网络能够在新的毫米波传输频段中高效运行。该研究将对解决未来20至30年的无线容量瓶颈，并使英国保持在毫米波技术和创新的前沿产生深远的影响。
