Obiettivi dell'insegnamento

The goals of the course are (i) to teach students the peculiar characteristics of wireless communication (in the wider area of digital communications), (ii) to make students able to understand and apply the techniques for addressing the challenges in the design of a wireless communication system and (iii) to make students understand the reasons behind the fundamental solutions adopted in the current advanced wireless technologies. In fact, with respect to other physical media, wireless communication is supposed to face three fundamental issues: very limited available frequency bandwidth, fading and signal dispersion phenomena in the channel and interference generated by coexisting signals. The course provides the instruments for modeling these aspects and understanding their impact on performance, and the technological solutions for addressing or limiting them. Each topic related to the use of specific models is treated both theoretically and practically; a part of the activity will be devoted to the development of simple projects in the laboratory sessions. Some topics will be presented also by exploiting approaches of the innovative teaching, especially for preparing the laboratory activity.

Risultati di apprendimento attesi

1-  Knowledge and understanding

Students will learn how to:

- define mathematical and statistical models for the analysis of wireless channels;

- analyze performance of digital modulation scheme in presence of random fading;

- analyze performance and limits of the fundamental solutions for wireless communication: diversity techniques, multiple antennas, adaptive systems;

- identify trade-offs between performance and design requirements;

- identify the role of system components and their relations.

2-  Applying knowledge and understanding

Students will be able to:

- dimension the fundamental parameters (bandwidth, power, modulation, ...) of a radio transceiver given the performance requirements;

- evaluate the performance of a wireless link in different propagation environments;

- apply the mathematical and statistical models learned.

3-  Making judgements

Students will be able to:

- understand the fundamental tradeoffs in the design of wireless systems;

- identify how the wireless channel characteristics impact the design of the system and its performance

- recognize the design potential of advanced wireless technologies (e.g. multiple antennas, cooperation, smart resource allocation).

4-  Communication

- Describe, exploiting also appropriate mathematical formulations, a wireless technology or a wireless communication topic at different levels of detail.

- In the case of a project, present an advanced topic with a brief presentation and talk (not mandatory).

Students are required to know the principles of communications systems and digital communications. They are also expected to have a basic knowledge of probability theory.

Modalità di valutazione

The assessment is based on the following three components, generally completed by an oral discussion:

1- a written exam on the theoretical part of the course with 3-4 questions, which is the basis for evaluating how the fundamental concepts have been assimilated and the capability of managing the theoretical tools. This part is mandatory and it gives till to 21 points in the final score.

2- A written exam with 1-2 problems, which reflects the activity and the solutions presented during the exercise hours in the course. This part is included in the same text with part 1) but it is not mandatory. It gives till to 6 points in the final score.

3- A laboratory project, in Matlab, assigned by the teacher and developed according to the tools and solutions presented and discussed during the laboratory hours in the course. This part is not mandatory and it gives till to 6 points in the final score. The projects will be assigned around the mid-semester, before starting the laboratory hours or later, upon request of the student. 

An oral for the discussion of the written exam and of the laboratory project (if present) typically concludes the exam. An oral can be requested also by the student.
