Welcome to the Advanced Wireless Systems Group. Our group focuses on both experimental and theoretical aspects of research related to wireless communications and network systems.
A main research focus on the group over the past decade or so has been physical-layer network coding (PNC), a wireless- networking concept first put forth by the group in 2006. PNC research in the group will be tapering down. Instead, a focus will be on potential commercial exploitation of PNC.
AI-driven wireless communications system and wireless networks.
Industrial wireless networks for IIoT communication (particularly specialized clean-slate network designs for the factory setting rather than Wi-Fi or 5G networks for general applications).
Network protocol and network architecture designs for blockchain, with the aim to boost transaction throughput.
(see Research for more details).
Some representative publications by the group in these directions are as follows:
