This study explores how project-based learning in combination with other pedagogical scaffolding approaches influences students' experiences during their transition into the university. Based on the thematic analysis of interviews with students at the end of the first semester, we show how a project-based course in electronics can create opportunities within three themes: student socialisation, curriculum integration, and peer-learning. In the light of these findings, we discuss how students build relationships with other students, as well as with faculty members and practicing engineers, and how these relationships influence their start at the university. On a more general level, this case study exemplifies how an existing electrical engineering programme can be changed by targeted interventions without the need for programme wide adjustments.
Carrier frequency offset (CFO) in OFDM/OQAM systems can be estimated based on the conjugate correlation function of the received signals. Traditionally this is done before demodulation. We present new methods based on the subchannel signals. The proposed estimators are robust to multipath effects due to the narrowband property of the subchannels. The performance of the estimators is evaluated by asymptotic analysis and simulation results. Our results show that methods based on estimation in subchannels have better performance than estimators operating before demodulation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
