Objectives

This course aims to motivate students to fundamental and advanced signal processing concepts and techniques in the areas of spectrum estimation, adaptive filtering, sonar, radar, and synthetic aperture systems. In addition to invoking the state of the art in these areas, it is also intended to address current research trends.

Learning outcomes and competences

The objective is to empower students with analysis and design skills in a variety of technologies and application areas including robust signal modeling, estimation, detection, and communication, as well as robust monitoring and detection of signals, objects, and environmental conditions. The ability to formulate and undertake research objectives is also encouraged through the autonomous search for information in the literature and the survey of the state of the art.

Teaching methods and learning activities

The topics of the curricular unit will be explained and discussed in lectures (one 3-hour class per week) where applied exercises and case studies illustrating the techniques and technologies in focus and based on signal processing will be addressed. These exercises and case studies will also be the object of specific home assignments that will contribute to assessment. Relevant teaching materials will be made available to students on the Moodle platform.

Eligibility for exams

Attendance in the curricular unit is recognized for students who do not exceed the limit of absences (established in the FEUP General Evaluation Rules) and who have participated in at least 70% of the assessment moments/elements specified throughout the semester.

Calculation formula of final grade

The final grade will be obtained by averaging the grades obtained in mini-tests, specific homework assignments, and/or mini-projects to be developed in groups of students throughout the semester.
