During my master's degree at Queen's, I had the privilege to supervise senior undergraduate students during their summer research internships.
She analyzed the performance of different wavelet-basedtechniques that can be applied to determine the spectrum occupancy, i.e., which bands have presence of primary networks and which bands are underutilized.
She worked on cooperative spectrum sensing in heterogeneous cognitive radio networks, where the cooperating secondary users have different sensing capabilities.

He worked on the economic aspects of spectrum management in cognitive radio networks.
She proposed a new softened-hard
combining technique for cooperative spectrum sensing, which is a compromise between the soft- and hard-based decisions.
