AIR TRAFFIC MONITORING AND TRACKING
Advisor: prof. Mattia Brambilla, prof. Monica Nicoli
Keywords: WAM systems, Thales Italia, Localization, Aircraft monitoring, Automatic Dependent Surveillance - Broadcast (ADS-B)
The focus of the research is the design of localization infrastructures and algorithms to augment the performance of aircraft monitoring and tracking during the critical phases of landing and departure. Localization technologies currently used in airports rely on local and wide area multi-lateration (WAM) systems. These, however, suffer from limitations due to the inability to resolve multipath ambiguities, the lack of optimization strategies for ground stations' selection, calibration issues and limited coverage. The PhD research aims at the development of enhanced solutions to overcome such limitations, by extending the system coverage in areas such as open sea and mountain areas, allowing to offer a service where now it is not possible. To achieve this goal, the research will analyze hybrid WAM systems, where satellite stations are integrated with the ground stations, as well as where ground-based sensing technology (i.e., radar) is integrated with Automatic Dependent Surveillance - Broadcast (ADS-B) messages.
HARDWARE ACCELERATION OF OPEN RAN FOR DIGITAL TWIN APPLICATIONS
Advisor: prof. Maurizio Magarini
Keywords: Radio Access Networks (RAN), Digital Twins, FPGA
From current research trends new generations of the cellular network will have greater and greater environment sensing capabilities. Techniques and algorithms for joint sensing and communications are being developed in ad-hoc solutions which are not standard compliant. On the other hand, Radio Access Networks (RAN) are also evolving towards more modular and customizable paradigms culminating in the idea of Open RAN, a completely interoperable enabler of new technologies for RAN. From the fusion of these two worlds emerging technologies like Digital Twins promise new and exciting applications. Bridging the gap between them, however, is a challenging task. It requires the execution of complex processing for sensing the environment within extremely tight time budgets to ensure low network latency.Thus, the goal of this research is to develop new enablers for these applications which are capable of meeting and exceeding such harsh requirements by developing FPGA images which enable sensing applications while exposing them through O-RAN interfaces. The challenges and prospects of using O-RAN for real-time operations will be explored, along with defining potential integration solutions for sensing applications. Finally, experimental verification with state-of-the-art hardware for the developed FPGA code will be performed.
Advisor: Any faculty member can act as research advisor

The research field Telecommunications is focused on the design and implementation of devices, systems, networks (Internet, wireless networks, optical networks), services, and applications for the transmission and the processing of any type of signals (including audio, video, RADAR) and multimedia information. Particular attention is given to advanced networks and transmission systems for mobile and fixed users and to remote sensing applications aiming at earth observation and sub-soil exploration. The strong connection with leading companies (within and outside the telecommunication market) makes the mix between theory and application one of the strengths of the Telecommunications research field at Politecnico di Milano.
