About the Lab

Cognitive Communications Systems Laboratory (CCSL) aims to apply perceptive, adaptive and learning-based approaches to design modern wireless communications systems. First, we are interested in developing efficient algorithms to achieve ultra reliability, low latency and high throughput for wireless networks. We also delve into self-organizing networks, which are powered by cognitive operations among devices and energy harvesting technologies. Lastly, we seek for novel methods of information protection, legitimate surveillance, and covert communications.
To this end, the members of CCSL have an opportunity of mastering mathematical tools such as linear algebra, linear/non-linear programming and machine learning. They can also develop their programming skills to implement or set up simulation environments of wireless systems.
