Fundamentals of signal theory, signal processing, and communication theory

Lecture notes prepared by the instructors as part of the monograph "Wireless Access in Communication Networks". Scientific articles for further study selected by the instructors.

The course is structured in lectures that treat course topics, combining an accurate analytical description of each topic with examples of use of studied techniques and protocols in both existing networks and new networks currently being developed. Lectures introducing each topic are complemented by lectures in which the topic is analyzed as part of design and dimensioning of a wireless network. Active participation by students to such lectures is highly encouraged, and intended as a mean for them to verify their comprehension of course topics. Based on the directives provided by Sapienza during the semester, classes are held either in presence or remotely on Zoom at the link https://uniroma1.zoom.us/j/88345130247?pwd=cTViNUtaZGtDTFdBR3FrcmVsMVBiUT09

Class attendance is optional, but highly recommended.

The exam consists of a written test, which involves developing a project using the simulation tools taught during the course (Matlab, Octave), and an oral exam focused on the content of the lectures and exercises conducted in class. Both parts have equal weight in determining the final grade.

The course includes traditional lectures that present the topics covered, combining an in-depth treatment of analytical aspects with examples of how the studied techniques and protocols are applied in existing and emerging wireless networks. Each topic is introduced through theoretical lectures, followed by sessions where the topic is analyzed in the context of one or more problems related to the analysis and dimensioning of a wireless network. Active student participation in these sessions is strongly encouraged, as it allows them to test and consolidate their understanding of the subjects covered in the course.
