Modeling, design and experimental implementation of digital transmission systems


The design of next generation transmission techniques over optical fiber or wireless links is a complex process that requires a research flow that starts from the modelling and simulation of the involved physical channels and the analysis of the transmission and detection options and evolves towards experimental demonstrations. Advanced modelling techniques are required and, nowadays, they are more and more based on innovative Artificial Intelligence algorithms. Final targets of this research are one or more of the following: increase in bit rate, increase in maximum distance and coverage, reduction in overall energy consumption and increase in transmission reliability and security.
Typical applications are ultrabroadband optical fiber networks, 4G/5G and future 6G wireless links and space/satellite communications.
Another very promising application of this field is Quantum Key Distribution (QKD) to obtain intrinsically secure cryptographic transmission of digital information, which is usually obtained using quantum technologies on optical components and optical fibers.
