Communications & Signal Processing


The Communications and Signal Processing Laboratory integrates individual faculty-led research groups in a modern facility occupying nearly an entire floor of Walter Light Hall. The Lab’s research activities are directed towards enabling future generation communications systems, networks, and devices, such as Internet of things, 5-G networks, self-driving vehicles, and intelligent assistants. You are invited to explore the research interests of the groups, listed below with web links to the groups’ web pages.

As a highlight, the Lab’s activities include the design and optimization of next generation wireless communications systems. Advanced technologies are developed for emerging and future wireless W/M/L/P/HANs, ad hoc networks, sensor networks, medical networks, biologically-inspired networks, nano-scale networks, industrial networks, and heterogeneous wireless networks. Activities include developing theories and techniques to solve critical problems such as signal detection and estimation, cognitive radio, multiple antenna systems, wireless cooperative diversity networks, mobile WiMAX systems, and indoor and outdoor navigation. Another domain of activity, human-centered communications, entails devising machine intelligence for processing, understanding, and distributing multimedia signals. Advancements stemming from the activities run the gamut from new findings in information and communications theory to practicable algorithms and hardware architectures.

Members of the Lab have won major research grants, paper awards, and professional recognitions. They are actively engaged in research collaborations with universities and companies locally, domestically, and globally. The Lab constantly hosts a sizable group of visiting researchers and students. Lab members also regularly serve as conference organizers and as editors of top international journals, including IEEE Transactions on Communications, and IEEE Transactions on Wireless Communications, and IEEE Transactions on Speech and Language Processing.

A synopsis of our history: Communications research at Queen's is synonymous with the development of the communications industry in Canada. Queen’s ECE Department is located in Walter Light Hall, a building named after Queen's ECE graduate Walter Light, who was a CEO of Northern Telecom (the former Nortel, for decades a global telecom industry leader and the biggest industrial R&D enterprise in Canada). The Queen's radio station, CFRC, was pioneered by ECE in the 1920s, and is among the oldest broadcast radio stations in Canada. Queen's ECE also initiated the Biennial Symposium on Communications in 1962. Regarded as Canada's premier conference in communications research, BSC was held in Kingston for more than half a century before relocating to other Canadian venues in 2016.

Over the years, Queen's ECE graduates have gone on to become influential members of the Canadian & US telecommunication industry: companies such as Sycamore Networks, Bell Canada, Bell Mobility, and Nortel. The first female Ph.D. graduate served as President of the Communications Research Centre, for decades the largest Canadian government research laboratory. Moreover, numerous Ph.D. graduates have successful academic careers as professors in universities around the world.
