Communication networks rely on a range of communication media that can be wireless, wired, optical etc., to transmit, retrieve and process data. Constraints are generally placed on the tasks that need to be carried out. These constraints take into account a number of performance metrics, such as complexity, reliability, latency and secrecy. Depending on the nature of the network, they can be addressed in a centralized or in a decentralized way.
Over the past five years, the Digital Communications team has focused its research work on gaining a better understanding of the fundamental limits of communication networks and devising the means to reach them.
The Digital Communications (ComNum) team is particularly active in the following areas:
- Point-to-point co mmunications
- Network optimization
- Communications and device security
- Interdisciplinary tools derived from information theory and statistics
