Research activity

Dr Font-Segura's experience in undergraduate research includes the improvement of a spectrum estimation technique for in-orbit satellites in a project funded by Indra Espacio SA, as well as introducing a water-filling like algorithm for multi-user downlink communication through multiple-input multiple-output orthogonal frequency division multiplex (MIMO-OFDM) channels based on Tomlinson-Harashima precoding. Awarded by a prestigious "la Caixa" fellowship, he spent a one-year research program at the Signal and Information Processing Group at Columbia University, New York, involving fundamental research on multi-user communication and a novel spectrum sensing technique for cognitive radio based on the generalized likelihood ratio testesting (GLRT) and attending various seminars and distinguished lectures on a broad range of telecommunication topics. In September 2009, he joined the Signal Processing and Communications Group at UPC as a PhD candidate focussing on the compressed-sampling applied to spectrum sensing for cognitive radio in wideband regimes. In October 2014, he joined the Information Theory and Coding Group at UPF as postdoctoral researcher. Dr Font-Segura is a recipient of the Best Paper Award for the Signal Processing for Communications Symposium at the 2013 IEEE International Conference on Communications (ICC), Budapest, Hungary.
