Advanced Wireless Communications Techniques for 5G Networks

第四代蜂窝技术（4G）已无法满足物联网和超高清视频流等新兴无线应用的不断需求。预计在未来十年，数万亿的移动的通信设备将连接人与人、人与机器、机器与机器，形成一个数字连接的社会，任何人或任何东西都可以随时随地访问信息。要充分实现这一水平的连通性和网络能力，就必须建立新的基础信息基础设施。因此，存在一致的努力来定义新的第五代（5G）技术，其在吞吐量、延迟和连接性方面具有10倍至100倍或更多的显著改进的性能要求。然而，提高无线网络性能的一个重大障碍是优质微波频谱的稀缺。设想5G网络克服这些限制的两种潜在方法是：i）通过使用更加丰富的毫米波（MMW）频谱来补充微波频谱，以及ii）通过部署先进的介质接入共享技术，例如非正交多址（NOMA）。 本文提出的研究计划将全面研究集成双微波/毫米波无线网络以及NOMA，以实现满足新兴应用需求的5G网络。研究计划从实践到理论，从实用算法和信号处理的设计到基本限制的理解。 这包括了解集成微波/毫米波网络的局限性，以及如何实际配置这种网络以获得最佳性能，以及NOMA的实用算法和信号处理，以及如何为集成微波/毫米波无线网络配置NOMA。 本文提出的研究计划将产生重大的影响和效益。首先，该研究计划将直接影响几个本科生，硕士和博士生在加拿大大学通过他们接受的培训和未来的职业生涯，这种培训使。 其次，加拿大缺乏高素质和训练有素的5G技术人员，该计划将通过提供具有所需先进专业知识的人员来帮助加拿大工业。该研究计划将在克服5G技术的技术挑战方面取得重大进展，并将有助于对无线网络的科学理解。此外，无线网络和蜂窝网络特别地在很大程度上由于它们向其终端用户提供的连接性、移动性和应用而变得无处不在。随着5G带来的新应用，这些对社会的好处将大幅增加。

Fourth generations cellular technology (4G) can no longer meet the unrelenting demands of new emerging wireless applications such as Internet-of-Things and ultra high definition video streaming. It is expected that in the next decade, trillions of mobile communication devices will connect people to people, people to machines, and machines to machines, forming a digitally connected society in which anyone or anything can access information anywhere, at any time. Fully realizing this level of connectivity and network capacity necessitates the creation of a new underlying information infrastructure. Thus, there is a concerted effort to define a new, fifth generation (5G) technology with significantly improved performance requirements of 10x to 100x or more in terms of throughput, latency, and connectivity. However, a significant impediment to improving the performance of wireless networks is the scarcity of quality microwave spectrum. Two potential methods by which 5G networks are envisioned to overcome these limitations are i) to complement microwave spectrum through the use of millimeter wave (MMW) spectrum that is significantly more plentiful, and ii) through the deployment of advanced medium access sharing techniques such as Non-Orthogonal Multiple Access (NOMA). The research plan proposed here will take a holistic view of the study of integrated dual microwave/MMW wireless networks as well as NOMA for the realization of 5G networks that meet the demands of new emerging applications. The research plan spans from practice to theory, from the design of practical algorithms and signal processing to the understanding of fundamental limitations. This includes thrusts on understanding the limitations of integrated microwave/MMW networks and how to practically configure such networks for optimal performance, as well as practical algorithms and signal processing for NOMA and how to configure NOMA for integrated microwave/MMW wireless networks. The research plan proposed here will have significant impact and benefits. First, the research program will directly impact several undergraduate, master's and PhD students at a Canadian university through the training they received and the future careers that this training enables. Second, there is a dearth of highly qualified and trained personnel in 5G technology in Canada, and this program will help Canadian industry by supplying personnel with the required advanced expertise. The research plan will make significant progress to overcoming technical challenges to enabling 5G technology, and will contribute to the scientific understanding of wireless networks. In addition, wireless networks and cellular networks in particular have become ubiquitous in large part due to the connectivity, mobility and applications they provide their end users. With the new applications enabled by 5G, these benefits to society will increase dramatically.
