The activity of the ASIP Department is mainly focused on fundamental and applied research in signal processing and information theory, giving special emphasis to wireless communications. Our main objective is to contribute to spectrum sharing techniques for bandwidth-hungry service deployments in future 5G mobile communication systems. We specifically cover the design of novel transmission techniques in order to increase the spectrum efficiency while reducing the amount of energy that is employed for the transmission of each bit.
In order to tackle these challenges, the ASIP Department proposes to set up three research lines of rather theoretical nature, namely:
- Post-OFDM filterbank multicarrier (FBMC) modulations for 5G wireless communications.
- Novel paradigms in multi-antenna signal processing.
- Energy Harvesting Communication and Sensor Networks.
A transversal research line on prototyping of PHY communication systems is also established, which specifically focuses on implementation solutions for wireless communications and power line technologies.Scientific Publications & Patents
