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.

近年来，越来越多的全球IP流量是由消费者产生的，这促使容量的增长和延迟的减少。为了满足这些要求，正在研究第五代无线技术，以支持1000倍的容量增长，连接至少1000亿台设备，并提供10 Gb/s的个人用户体验，具有极低的延迟和响应时间。拟议的研究重点是第五代无线系统的微波光子技术的发展。特别地，将研究基于光空分复用（SDM）的多输入多输出正交频分复用（MIMO-OFDM）光纤无线接入架构。为了降低系统的复杂性，提高系统的性能，将发展相关的微波和光学器件，其中光子集成将发挥重要作用。具体而言，将研究和开发包括激光源、调制器和光电探测器的发射器和接收器的混合集成。还将开发混合光电振荡器作为微波频率上转换的高质量微波源。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。这项工作将对第五代无线通信系统产生巨大的影响。这一项目产生的新知识和对与工作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。
