I received my B.Sc in Computer Science, Electronic And Communication Engineering, and M.Sc. in Communication Engineering at the University of Parma in 2018 and 2020, respectively. Under the supervision of Prof. Alessandro Ugolini and Prof. Giulio Colavolpe, I presented my Master Thesis titled "Constellation Design for Non-linear Channels", focusing on the performances of some constellation design for modulation, in particular the spiral constellation.
From Febraury 2021 to August 2021, I received a Research Fellow Scholarship from National Inter-University Consortium for Telecommunications (CNIT) for the topic "Design of Multicarrier Modulation Formats for 5G Systems".
Under the supervision of Prof. Gerhard Kramer, I am currently conducting research on 6G Wireless Communication models, in particular using Intelligent Reflecting Surfaces (IRS), and Information Theory.
I may not always have prepared thesis topics available. Please feel free to reach out if you are interested in working on a thesis within any of my research areas.
Prerequirements:
Intelligent reflecting surfaces (IRS) have been considered a novel technology for 6G wireless communications. They allow to have a reliable transmission in scenarios where the LOS communication is not available (e.g, in case of blockage) [1]. They also allow to perform Integrated sensing and communication [2].
A very important scenario in which the IRS can be useful is the Multi-user one, where a BS is communicating with multiple UEs. In this case the IRS can be used in order to perform channel estimation or to improve the communication quality by increasing the Beamforming quality [3-4-5].
The task of the student is to make a literature review based on this case scenarios, in order to give an overview on the pros and cons of those technologies. The student can focus either on the channel estimation side or the beamforming one.
