Conoscenze

This course is on statistical signal processing, at a senior or first-year-graduate level. The goal is to provide the theoretical tools to study advanced topics in communication theory and digital signal processing such as: parameter estimation of a signal embedded in noise, correct retrieval of a signal message from data corrupted by disturbance sources, spectral analysis, parametric modeling, estimation of random processes, with applications to radar and digital communications.

Modalità di verifica delle conoscenze

During the written exam (2 hours), the student is asked to solve four exercises in order to demonstrate the ability to put into practice the basic principles of deterministic and statistical signal theory illustrated throughout the course. During the oral exam, the student will be assessed on his/her ability in discussing the main course contents with competence, critical awareness and propriety of expression.

Methods:

  • Final oral exam
  • Final written exam
