About
The Advanced Optical and Wireless Research Laboratory hosts research students and postdoctoral fellows working under the supervision of Professors Octavia A. Dobre, Trung Q. Dung, and Ibrahim Al-Nahhal. They tackle important problems in wireless and optical communications systems, e.g., related to the integration of terrestrial and non-terrestrial networks, integration of sensing and communications, AI for communications and networks, quantum optimization and quantum machine learning for communications and networks, resource allocation, signal intelligence, optical performance monitoring, and fibre nonlinearity compensation.
The equipment in the Advanced Optical and Wireless Research Laboratory supports the testing of high-performance algorithms developed by the research group, related but not limited to:
- Aerial and terrestrial communications
- Spectrum monitoring and signal identification
- Parameter estimation, signal detection, and interference cancellation
- Optical performance monitoring and fibre nonlinearity compensation
