Millimeter-wave (mmwave) communication technology (MCT) is key to unlocking new/expanded features and capabilities required by numerous domains including terrestrial and mobile satellite communication, autonomous vehicles, and augmented and virtual reality. Nevertheless, the full realization of these capabilities is predicated on the availability of commercially viable mmwave large-scale multiple antenna (LSMA) hardware capable of achieving ultra-reliable and efficient links for a wide range of MCT use cases. For example, mmwave LSMAs are expected to improve the precision of vehicle localisation by using multi-beamforming and to enable high-speed directed links between vehicle-to-everything. Similarly, mmwave LSMAs are compelling technology for AR and VR enabled applications in diverse sectors such as medicine, education, consumer retail, urban design, advanced manufacturing, and entertainment. ***Existing mmwave LSMA hardware is expensive, highly complex, and only allows for limited reconfigurability. In addition, research into MCT has largely relied on several optimistic simplifying assumptions including the existence of accurate channel state information and distortionless, low power, and low-cost mmwave LSMA hardware. Hence, preliminary commercial trials are not achieving the full potential of MCT and many experimental trials are yielding sub-optimal results in terms of cost, power consumption and quality of signal. Addressing these limitations will require significant advances in mmwave LSMA and baseband digital signal processing.***The requested equipment, a quad-channel high-performance streaming arbitrary waveform generator (HPS-AWG), is not accessible in Canada. Contrary to conventional AWGs, the requested equipment allows unprecedented capacity to generate and analyse non-repeating, high quality (12 bits) and wideband (5 GHz) signals for hours. When combined with existing equipment, the HPS-AWG will form a testbed that allows researchers to carry out comprehensive end-to-end over-the-air proof-of-concept validation of theoretical research outcomes. The high programming level of the modules will mean the testbed can be easily configured to support research into various aspects of MCT including millimeter-wave physical-layer link analysis, architecture and algorithms and baseband digital signal processing.***The requested equipment is critical to the internationally competitive research programs of the applicants. Outcomes of these programs (new analyses, models, algorithms and prototypes) are essential to the applicants' multinational industry partners. In addition, about 12 students and postdoctoral fellows will develop knowledge and practical skills at the very leading edge of the MCT evolution. The outcomes made possible with the requested equipment will help us realize the benefits of MCT to meet the staggering demands imposed by the digital transformation of service provision in the communication, transportation and entertainment sectors.

毫米波 (mmwave) 通信技术 (MCT) 是解锁地面和移动卫星通信、自动驾驶汽车以及增强和虚拟现实等众多领域所需的新/扩展特性和功能的关键。然而，这些功能的全面实现取决于商业上可行的毫米波大规模多天线 (LSMA) 硬件的可用性，该硬件能够为各种 MCT 使用案例实现超可靠和高效的链路。例如，毫米波 LSMA 有望通过使用多波束成形来提高车辆定位的精度，并实现车辆与万物之间的高速定向链接。同样，毫米波 LSMA 是一项引人注目的技术，适用于医学、教育、消费零售、城市设计、先进制造和娱乐等不同领域的 AR 和 VR 应用。 ***现有的毫米波 LSMA 硬件价格昂贵、高度复杂，并且仅允许有限的可重新配置性。此外，MCT的研究在很大程度上依赖于一些乐观的简化假设，包括准确的信道状态信息的存在以及无失真、低功耗和低成本的毫米波LSMA硬件。因此，初步的商业试验并未充分发挥 MCT 的潜力，并且许多实验试验在成本、功耗和信号质量方面都产生了次优结果。解决这些限制需要在毫米波 LSMA 和基带数字信号处理方面取得重大进展。***所需的设备，即四通道高性能流式任意波形发生器 (HPS-AWG)，在加拿大无法获得。与传统的 AWG 相反，所需的设备具有前所未有的能力，能够生成和分析非重复的高质量（12 位）宽带 (5 GHz) 信号长达数小时。当与现有设备结合时，HPS-AWG 将形成一个测试台，使研究人员能够对理论研究成果进行全面的端到端无线概念验证。模块的高编程水平意味着测试台可以轻松配置，以支持 MCT 各个方面的研究，包括毫米波物理层链路分析、架构和算法以及基带数字信号处理。***所需的设备至关重要申请人的具有国际竞争力的研究项目。这些项目的成果（新的分析、模型、算法和原型）对于申请人的跨国行业合作伙伴至关重要。此外，大约 12 名学生和博士后研究员将在 MCT 发展的最前沿发展知识和实践技能。通过所需设备实现的成果将帮助我们实现 MCT 的优势，以满足通信、交通和娱乐领域服务提供数字化转型带来的巨大需求。
