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.

This course introduces the most important state-of-the-art techniques used in modern wireless and wired communication systems, taking 5G as a case study. 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 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.
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.

Modalità di esame: Prova orale facoltativa; Elaborato progettuale individuale;
Exam: Optional oral exam; 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: Optional oral exam; Individual project;
The scope of the exam is to verify that the students have acquired the basis of 5G communication systems, know the most important 5G blocks and are able to develop Matlab project on them. The exam is organized as follows:
The course is divided in 6 topics (Introduction, OFDM1, OFDM2, 5Gblocks1, 5Gblocks2, Beamforming). For each topic an assignment (to be solved individually) is proposed. The student must deliver a pdf report containing all the results, the figures and the required answers and all the written Matlab programs. Each assignment is evaluated and receives a mark (max mark = 30). The students who deliver their assignment withing 2 weeks from when it is assigned received 2 more bonus points (max mark = 32), to encourage the students to stay aligned to the course.
If the student does not deliver the assignment of a topic, must have an oral exam on that topic. A question
is extracted from a list presented at the end of the topic (typically consisting of 15 questions). The max mark for the oral question is 30.
Then, the student can deliver 6 Matlab assignments and have no oral exam, or 0 Matlab assignments and have 6 oral questions, or a 5 Matlab assignments and 1 oral question or any other combination.
At the end of the course the mean value of the assignment (or oral) marks is computed.
An extra assignment (or an extra list of questions) is proposed to students who want to further increase their mark (max +3/30 for the final mark).
Students who get at least 33 receive 30 cum laude.
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.

Written exam on course¿s topics (two hours and seven questions, no books, no notes, highest mark = 30 cum laude).
The assessment is made of 6 questions randomly extracted from a list prepared at the end of the course containing about 50 questions. These questions reflect key understanding the students should possess on the studied systems, the constituent blocks of their physical layer, and their most important applications. Each question is evaluated from 0 to 5 points.
A seventh question is also proposed, randomly extracted from a restricted list of 10 questions covering proofs and demonstrations of the techniques presented through the course, and is evaluated from 0 to 3 points.
The final mark is the sum of the marks obtained with the 7 questions. The students who get at lest 32 are awarded with 30 cum laude. The exam is 2 hours long, closed book.
