Hours 48
Period I
Language ENG

Prerequisites
To better address the study of the course contents, the student should have acquired at least the basics knowledge of electromagnetic fields, telecommunications and signal processing.

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
 Through the study of the most important telecommunication systems, the course enables students to acquire knowledge needed to understand the issues relating to transmission of information, and to know how to apply appropriate design procedures of communication systems. The course, by integrating the knowledge gained in previous courses like electromagnetic fields, telecommunications, and signal theory, provides the student with a solid technical background on communication systems.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
This ability will be developed in practice through a number of vocational skills, such as: 1. the ability to correctly choose the appropriate transmission medium, and the associated system architecture, to meet the system requirements; 2. the ability to identify and properly quantify the parameters necessary for the dimensioning of the system; 3. the ability to identify the causes of performance degradation, and the suitable countermeasures.
TRANSVERSAL SKILLS:
(ENG) Training activities and laboratory sessions will help improve the student’s ability to learn independently and to draw conclusions. Both the student’s ability to communicate and his/her independence of judgment in general, will be stimulated and refined, through oral discussions.

Program
Introduction to communication systems. Description of systems (fixed and mobile, free and guided propagation). Reception quality (bit error rate, delay, jitter). Noise effects on the received signal (thermal noise and artificial noise). Bit, frame and carrier synchronization. Block scheme of transceivers. Adaptative equalization at intermediate frequency and at base band. Spread spectrum techniques. Multiple access techniques. Systems on twisted pairs. ADSL. Fiber optics communications. Optical devices. Optical link budget. Line-of-sight radio systems. Link budget in fade environment. Mobile radio propagation. Planning of mobile radio systems. Description of GSM, GPRS and UMTS.

Development of the examination
LEARNING EVALUATION METHODS
The assessment of student learning consists of two parts: - A written test, which requires the solution of two or three exercises on topics covered in the course, to be completed in two hours; - An oral test, consisting in the discussion on one or more topics covered in the course (including lab sessions), and in the deepening of any gaps identified in the written test. Some questions posed during the oral may require the execution of short calculations. The written test is mandatory for the oral exam, it is advisable to take the oral exam after having obtained at least the minimum mark in the written test. The oral examination must be taken in the same appeal of the written test. In case of failure of the oral exam, the student must also repeat the written test.

LEARNING EVALUATION CRITERIA
In order to successfully pass the assessment of learning, the student must demonstrate, through the trials described above, that he/she possesses the knowledge and methodological skills for the characterization of the main telecommunication systems, the definition of their requirements and performance, the selection of the most suitable solution in relation to specific application needs. To successfully pass the oral exam, the student will demonstrate an overall knowledge of the course content (including lab sessions), presented in a sufficiently corrected way with the use of proper technical terminology. The highest rating is achieved by demonstrating a thorough understanding of the course content, exposed with complete appropriateness of technical language.

LEARNING MEASUREMENT CRITERIA
For both written and oral tests, a score between zero and thirty is assigned. The overall grade is given by the weighted average of the marks obtained in the two tests (accounting for 1/3 the result of the written test, and for 2/3 the result of the oral examination), with rounding to the greatest integer value.

FINAL MARK ALLOCATION CRITERIA
For the overall outcome of the exam to be positive, the student is advised to obtain at least sufficiency, equal to eighteen points, in the written test. And the student is required to achieve at least sufficiency (equal to eighteen points) in the oral test. The highest rating is achieved by demonstrating a thorough understanding of the course content under both tests. Praise is given to students who, having performed the tests correctly and completely, have demonstrated a particular brilliance in oral, and in the solution of the written exercises.
