The course is taught in English.
This course introduces the most important state-of-the-art techniques used in modern wireless and wired communication systems. The focus is on the system physical layer of mobile networks, from digital modulation to beamforming. The key techniques of 4G and upcoming 5G are analyzed with the aim of understanding their impact on different applications, and their possible evolution. This course is useful for all students interested to digital transmission, both in the Communications and Computer Networks Engineering Degree and in the Electronic Engineering Degree.
The course is given in English.
It introduces the most important state-of-the-art techniques used in modern wireless communication systems, from 1G to 5G, mostly on 5G technologies. The focus is on the system physical layer of mobile networks, from digital modulation to beamforming. The key techniques of 5G are analyzed with the goal of understanding their impact on different applications. This course is useful to all students who are interested in digital communications, both in the Communications and Computer Networks Engineering Degree and in the Electronic Engineering Degree.
At the end of this course, the students know the key characteristics of the considered communication systems, the most advanced techniques used for wireless and wired systems, and the practical scenarios and applications where they are used. In particular, they have an in-depth knowledge of the physical layer constituent blocks of: OFDM-based systems, 4G-LTE and 5G-New Radio systems. This way, the students acquire the ability to contribute to the design and the management of these state-of-the-art telecom systems.

Basic notions of digital modulations and signal processing.
Basic notions of probability, digital modulations, and signal processing.
Main topics of the course:
- Review of wireless systems: Digital modulations (PSK, QAM), coding, multiple access schemes, channel models (10 h)
- OFDM and modern techniques for wireless and wired systems (20 h)
- 4G LTE mobile networks: physical layer (10 h)
- New 5G systems physical layer: requirements, applications and technical solutions from modulation to MIMO and beamforming (20 h)
Main topics of the course:
- Introduction to mobile wireless systems up to 3G (15h)
- OFDM and modern techniques for wireless systems (15 h)
- 5G techniques including NOMA (15 h)
- Beamforming (15 h)
During the course we host seminars and presentations from ICT companies on state-of-the-art topics, offering thesis and internships, too. They introduce students to companies¿ vision on current and future systems.
The course structure is based on 4 main topics.
Each topic has a theoretical part followed by an assignment.
The assignment requires the use of a personal notebook for the solution of proposed Matlab exercises and the preparation of a report.
Teacher¿s material, available on the course web portal.

Book references are given at the beginning of the course
Modalità di esame: Prova orale obbligatoria; Elaborato scritto individuale; Elaborato progettuale individuale;
Exam: Compulsory oral exam; Individual essay; Individual project;

Written exam on course¿s topics (usually two hours and six questions, no books, no notes, highest mark = 30 cum laude).
The assessment is made of six questions randomly extracted from a list prepared at the end of the course.
Questions reflect key understanding the students should possess on the studied systems, the constituent blocks of their physical layer, and their most important applications.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam; Individual essay; Individual project;
The goal of the exam is verifying that the students have acquired the basic notions presented during the course and can develop a relevant Matlab project.
The exam is organized as follows:
For each of the four topics (Up to 3G, OFDM, 5G, Beamforming), an individual assignment is proposed. Students must deliver a pdf report containing all the results, the figures and the required answers and all the written Matlab programs. Each assignment is graded according to the time of delivery, maximum grade = 33.
The assignments are discussed during an oral exam.
The oral exam also includes one or two questions from the course program, maximum grade = 33.
The final grade is the average of the assignment grade and the oral grade.
If the grade is >= 31, it becomes 30 LODE.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
