Energy-Efficient adaptive transmitters for 4G wireless radio systems: New Design Paradigm and Enabling Techniques

无线通信领域中最迫切的需求之一是开发节能的、多标准、多协议的第四代(4G)无线无线电系统。这一需求是由泛在无线网络和动态频谱分配的需求驱动的，以解决频谱稀缺问题。此外，由于无线网络的碳足迹不断增长，能源效率也成为一个重要因素。要满足这一需求，就需要开发同时跨越多个频段的高能效无线电，每个频段的功率效率可与单频无线电相媲美。 建造节能自适应发射机的挑战将不仅通过开发新的系统架构和电路拓扑来解决，而且还将通过遵循综合研究战略来解决。因此，该项目的范围包括半导体器件的表征和建模，这两者都是实现无线电技术的巨大改进所必需的集成主干，而传统方法在器件表征和建模与微波电路和系统设计之间存在明确的界限。 这项工作将走在下一代无线技术的前沿，没有这一技术，这一部门根本无法满足新兴的需求。拟议的研究计划的灵感来自于加拿大、北美和海外工业的明确需求。在研究过程中，研究人员将寻求与学术界、产业界和政府机构合作的机会。需要建立各种伙伴关系，以确保项目成果符合需要，并尽可能以最全面、最严格和最有效的方式进行。

One of the most pressing needs within the field of wireless communications is the development of energy-efficient, multi-standard, multi-protocol, fourth generation (4G) wireless radio systems. This need is driven by the requirements for ubiquitous wireless networks and dynamic spectrum allocation in order to address spectrum scarcity. In addition, energy efficiency is also becoming an important factor due to the growing carbon footprint of wireless networks. Addressing this need will require the development of power efficient radios, which operate across multiple frequency bands concurrently, with the power efficiency for each of the frequency bands comparable to that of single-band radios. The challenge of building energy-efficient adaptive transmitters will be addressed by not only developing new system architectures and circuit topologies, but also by following an integrated research strategy. For this reason, the scope of the project includes semiconductor device characterization and modeling, both of which form an integrated backbone required to enable vast improvements in radio technologies beyond what has been possible with traditional approaches where clear boundaries have existed between device characterization and modeling and microwave circuits and systems design. This work will be at the forefront of the next generation of wireless technology, without which this sector simply cannot meet the emerging demands. The proposed research program is inspired by the expressed needs of industry in Canada, North America, and overseas. During the course of the research program, the researcher will pursue opportunities for collaboration with academia, industry, and government agencies. A diverse range of partnerships are required to ensure that the project outcomes meet the needs, and is carried out in the most comprehensive, rigorous, and effective manner possible.
