Basic concepts on signal theory, telecommunications and electomagnetic fields

Learning outcomes
Starting from the study of propagative conditions in contexts of greater importance, teaching enables students to acquire the knowledge necessary to understand the issues related to the solutions proposed in the wireless transmission of information systems, and to know how to apply the related design procedures . This knowledge, by integrating the knowledge gained in the teachings of telecommunications and electromagnetism, will provide the student with a solid technical background, combined with a working methodology that will operate in the areas of design of wireless systems.
In order to deal with advanced design issues, the student must be able to understand the effects of signals degradation in wireless communications and the system requirements, and to implement the correct design choices of engineering practice related to wireless communication systems. This capacity will be manifested through a number of vocational skills, such as: 1. the ability to appropriately choose the transmission technology, and the architecture of the system, to meet the capacity, coverage range and quality requirements; 2. the ability to quantify the magnitudes necessary for the dimensioning of the system, through the use of appropriate mathematical models and design tools; 3. the ability to identify the causes of performance degradation, and the countermeasures.
The solution of numerical examples for solving dimensioning problems of wireless communication systems, and simulations and practical experience of application issues, will help the student to improve its ability to learn independently and to draw conclusions. Both the ability to communicate that the degree of independence of judgment in general, will be stimulated and refined through the oral discussion of the issues related to the sizing and design of wireless communication systems.

Contents (Classroom lessons 60 hours): Mobile radio channel. Statistical and empirical models. Satellite communcations - link budget. TV Broadcast - DVB-S OFDM - DVB-T Spread Spectrum techniques - CDMA - GPS System. Ultra Wide Band Infrastructurebased wireless networks - GSM - UMTS - HSPA - LTE - 5G. The MIMO technology.

RADAR Software Defined Radio Laboratory activity (12 hours): Planning and test of a WiFi or Hiperlan radio link. Board programming for WSN.

Development of the examination
The exam consists of an oral test, during which the student is asked to present the main concepts and technological solutions related to the Wireless Communications. It will also be proposed to each student in-depth activity by carrying out a project on one of the topics covered in class, and concerning the design of a wireless communication system.

The student, during the oral test, will present and discuss the project developed (if present) and will demonstrate the knowledge and methodological and technological expertise for the design and dimensioning of wireless communication systems. To successfully pass the oral exam, the student must demonstrate an overall understanding of the 'teaching content, with a sufficiently corrected use of technical terminology. The highest rating will be achieved by demonstrating a thorough understanding of teaching content, exposed with complete mastery of technical language.

During the examination the student's independent ability to set and solve problems that are placed will be evaluated. It shall also assess the ability to use properly the relevant methodologies, models and technologies of Wireless Communications.

The highest rating is awarded to students who demonstrate during the exam, full autonomy to set and solve problems and complete mastery of the methodologies, models and technologies of Wireless Communications. The minimum grade is assigned to students who demonstrate during the exam, to be able to solve problems that are placed and sufficient knowledge of the methodologies, models and technologies of Wireless Communications.
