About Centre for Telecommunication Research
The Centre for Telecommunication Research is a research-based institution at the Sri Lanka Technological Campus (SLTC) dedicated to innovative, collaborative, and industry-sponsored research in wireless communications and networking.
Research activities at the CTR, both fundamental and applied, mainly focus on technologies related to the physical, data-link, and network layers of communication systems, as well as optical communication. This vision of CTR aims to perform globally competitively in both research and engineering.
Established in 2019, CTR is one of the leading active research centers in Sri Lanka. Under CTR, two major research groups are operating: the Wireless Communications Research Group and the Fiber Optics Research Group.
With respect to technology, CTR offers competence demonstrated by several international partnerships with countries including Russia, the US, Canada, Australia, France, Portugal, India, Pakistan, and the UK.
The CTR group is working on multiple state-of-the-art research areas related to 5G and beyond wireless communication and networking. Currently, the research group is focusing on cutting-edge technologies such as wireless power transfer (WPT), machine learning-based wireless communication, underwater visible light communications (VLC), unmanned aerial vehicle (UAV) assisted communications, non-orthogonal multiple access (NOMA) technologies for 5G, physical layer network coding (PNC) in multiple access techniques, age of information (AoI) in wireless networks, and reconfigurable intelligent surfaces for beyond 5G.
The Fiber Optics Research Group is working on non-linear phase noise compensation techniques, developing dispersion measurement techniques, and free space optics (FSO). Furthermore, this research group conducted a feasibility study on fiber network infrastructure development to implement South East Asia–Middle East–Western Europe 4 (SEA-ME-WE 4) traffic routing via Sri Lanka.
