Mathieu Léonardon

Associate Professor in Electronics

IMT Atlantique


I teach electronics in IMT Atlantique engineering school. My research at the IMT Atlantique in Brest concerns hardware and software implementations of signal processing and AI algorithms.

My PhD thesis focused on the implementation of polar codes decoders. I proposed the fastest software implementation of the Adaptive SC List decoding algorithm to date. This implementation is integrated in the AFF3CT toolbox to which I actively contribute. The second main theme was the proposal of flexible ASIP architectures specialized in polar decoding.
