Promotor: R.L. Lagendijk, Richard Heusdens

Expertise: Acoustic signal processing

Biography

Jorge is responsible for the development and accomplishment of the BSc Electrical Engineering curriculum. In particular, he is responsible coordinator for the "Autonomous Driving Challenge" in EPO-4, and its prerequisite, the Telecommunications A practicum. He is also a tutor in "Design a Chip" EPO-3, and its Integrated Circuits practicum prerequisite. He is also lecturer of Master level courses in the Sustainable Energy Technology and Signals & Systems tracks.

Jorge received his PhD degree from TuDelft in 2013. He specialized in acoustical signal processing. In particular modeling and simulation of "multi-channel room impulse responses", which is a characterization of how the sound field evolves in a given place. This has many uses in our modern society, from improved speech recognition in voice-controlled "intelligent personal assistants", to better noise reduction in your mobile phone, or to be able to understand the playing message at the train station even when the train arrives. Jorge actively research these and other related topics as a Research Fellow within the Circuits and Systems Group at TuDelft.

General signal processing

Generalized discrete Fourier transform (gDFT)

A generalized Fourier transform is introduced that enables linear convolutions without the need of zero-padding. This results in faster, more resource- efficient computations
