Development of an SDR prototype for the reception of TV and radio services with 5G technology (new posted on April 8th 2022)

The evolution of vertical services in the context of fifth generation (5G) specifications is leading to the definition of solutions for the distribution of linear/live TV and radio services with radio and core network technologies. This includes, for example, the possibility to distribute free-to-air services to receive-only devices. A first objective of the thesis work is to identify what restrictions and profiling exist in the 3GPP specifications for the deployment of such services over 5G cellular and broadcast networks. In a second phase, the work will focus on the development and design of a software-defined radio (SDR) solution to be deployed on hardware evaluation boards (USRP, Universal Software Radio Peripheral) for over-the-air reception of multimedia signals.

Going Beyond the Shannon paradigm: Semantic Molecular Communications (new posted on December 29th, 2021)

Communications primarily focuses on how to accurately and effectively transmit bits from the transmitter to the receiver. Typical performance metrics are bit or symbol error rate. With the development of cellular communication systems, capacity is gradually approaching to the Shannon limit. Semantic communications, which is inspired by deep learning technologies, is regarded as a promising research direction to improve the system efficiency and reduce the data traffic to convey the desired meaning and affect the receiver’s behavior. The goal of the thesis is to explore the concept of semantic communication with fundamental principles and performance metrics and its application to the context of molecular communication to describe the task-oriented behavior of free moving agents.

Analysis and characterization of the delay introduced by relays in 5G NR vehicular communications

The evolution of telecommunications networks with the arrival of the fifth generation (5G) entails the need for new infrastructures capable of meeting the requirements of new applications both in terrestrial communications, such as cellular (UE-UE) and vehicular (V2V), both in ground-to-air communications, such as drone-UE or drone-vehicle. One of the main aspects is the need to identify and define signal relaying strategies that meet the requirements of high reliability and low latency. The purpose of the thesis will be to study the pros and cons of current relaying strategies (starting from the most common ones such as Amplify & Forword, Decode & Forward) and their applicability in the new scenarios of 5G-New Radio.
