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，全球IP流量中消费者产生的流量越来越大，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5代无线技术，以支持容量增加1000倍，连接至少1,000亿台设备，以及能够极低延迟和响应时间的10 Gb/S个人用户体验。本次研究的重点是第五代无线系统中微波光子技术的发展。特别是，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)光纤无线接入体系结构。为了降低系统的复杂性，提高系统的性能，相关的微波和光学器件将被开发出来，其中光子集成将发挥重要的作用。具体地说，将研究和开发发射器和接收器的混合集成，包括激光源、调制器和光电探测器。混合光电振荡器也将被开发为高质量的微波上变频微波源。还将研究和开发使用硅基可调延迟线的基于实时延迟的相控阵波束形成。这项工作将对第五代无线系统产生重大影响。该项目产生的新知识以及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。
