Microwave photonic techniques for 5G

近年来，消费者产生的全球IP流量越来越多，这促使容量的增长和延迟的减少。为了满足需求，第五代无线技术正在研究中，以支持容量增加1000倍，连接至少1000亿台设备，以及具有极低延迟和响应时间的10gb /s个人用户体验。本文主要研究第五代无线通信系统中微波光子技术的发展。特别是，基于光空分复用（SDM）的多输入、多输出正交频分复用（MIMO-OFDM）光纤无线接入架构将被研究。为了降低系统的复杂性和提高系统的性能，将开发相关的微波和光学器件，其中光子集成将发挥重要作用。具体来说，将研究和开发包括激光源、调制器和光电探测器在内的发射器和接收器的混合集成。混合光电振荡器作为微波频率上转换的高质量微波源也将得到发展。基于硅基可调延迟线的真实时间延迟的相控阵波束形成也将被研究和开发。拟议的工作将对第五代无线系统产生巨大影响。从这个项目中产生的新知识以及对与工作的不同阶段有关的高素质人员的培训将有助于提高加拿大的全球竞争力，特别是在信息和通信技术部门。

In recent years, an increasing amount of the global IP traffic has been generated by consumers, which urges the growth in capacity and the reduction in latency. To meet the requirements, the 5th generation wireless technology is being studied to support 1000-fold gains in capacity, with connections for at least 100 billion devices, and a 10 Gb/s individual user experience capable of extremely low latency and response times. The proposed research focuses on the development of microwave photonic techniques for the 5th generation wireless systems. In particular, optical space-division multiplexing (SDM) based multi-input, multi-output orthogonal frequency division multiplexing (MIMO-OFDM) fiber wireless access architecture will be investigated. To reduce the system complexity and improve the system performance, the associated microwave and optical devices will be developed, in which photonic integration will play an important role. Specifically, hybrid integration of transmitters and receivers including laser sources, modulators and photodetectors will be investigated and developed. Hybrid optoelectronic oscillators as high quality microwave sources for microwave frequency up conversion will also be developed. Phased array beamforming based on true time delays using silicon-based tunable delay lines will also be investigate and developed. The proposed work will have dramatic impact on the 5th generation wireless systems. The new knowledge generated from this project and the training of highly qualified personnel associated to the different stages of the work will contribute to enhance Canada's global competitiveness, especially in information and communication technology sectors.
