The research group applies tools for the characterization, generation and processing of signals and data that focus and exploit the statistical features of the information to manage.
The approach is very general and considers tools from classical statistical analysis to statistical theory of chaotic dynamical systems, signal modulation techniques, discrete an continuous optimization, data-driven methods exploiting machine learning. This allows to tackle a wide range of applications, even not strictly in the IT field, in those disciplines in which the gathering and management of information brings benefit.
Many of the solutions developed are implemented as physical subsystems either in digital platforms or in application specific integrated circuits designed ad hoc.
As examples, the research group has addressed and/or is currently addressing these applications

Optimization of CDMA codes for asynchronous access
