About

Our group works at the intersection of Wireless Communication, Sensing and Networking (hence WCSNG). We develop theory and algorithms with special focus on implementation and protyping of solutions in our impact areas. Our current impact areas include: wireless localization, sensing for autonomous driving, sensing for healthcare, spectrum sensing for next-generation networks, and wireless systems for VR/AR applications.

We have a multi-discplinary team with collaborative efforts across ECE, CSE and MAE departments. The group has a strong foundation in signal processing, system design and modeling. We use a wide repertoire of software to verify our theory and approach. We routinely work with wireless radios, both off-the-shelf and those designed in house. Our members are also experienced in data gathering and use popular machine learning techniques to expose cross-layer solutions to problems.
