Statistics (First year, second semester) Systems and Circuits (First year, second semester) Students are also expected either to have completed or to be simultaneously enrolled at Linear Systems (Second year, first semester)

Knowledge and management of the basic concepts and techniques for digital and analog communication such as noise, modulation and demodulation processes in digital communications, the information theory as a tool to establish the limits in communication systems and the fundamental techniques for analog communications. Therefore, the subject has the goal of allowing the student to acquire the following general competences: * Knowledge and development of technical skills required in the telecommunications field with emphasis in the analysis and mathematical characterization of a communication system. The same way than the following specific competences: * Acquisition of the knowledge of mathematics and statistics that will be used as a tool to solve engineering problems in the context of communication systems. (PO a, PO e, and PO k) * The ability to design and conduct experiments, as well as to analyze and interpret data and results. (PO b) * Design of a communication system with the constraints given by its critical parameters such as cost, consume of power, bandwidth, transmission rate, and complexity. (PO c) * Ability of effective communication of information, in speech and in writing. (PO g)

C6_ECRT5: Ability to weigh the advantages and disadvantages of different alternative technologies for development and implementation of communication systems, from the point of view of signal space, perturbations and noise, and analog and digital modulation systems.

In order to cover the 6 ECTS credits of the course, the following learning activities are considered: 1) Theoretical¿practical lectures - 1.68 ECTS 2) Workshops and laboratory sessions - 0.32 ECTS 3) Individual or group work - 3.84 ECTS 4) Final examination - 0.16 ECTS The theoretical lectures consist of expository sessions that combine the use of the blackboard, projection systems, and audiovisual media to illustrate specific concepts. During these sessions, the explanation of theoretical concepts is complemented with the solution of exercises. Through these activities, students acquire the fundamental contents of the course. It should be emphasized that these lectures require initiative and both individual and group work from the students, as some concepts must be studied independently based on provided guidelines, and certain specific cases must be developed by the students themselves. In the practical or problem-solving sessions, students are provided in advance with the corresponding problem statements. The resolution of exercises by the students aims at consolidating the concepts presented in the theoretical lectures in a more applied context and also allows students to self-assess their level of understanding. Laboratory sessions mainly consist of demonstrations of the concepts covered in the theoretical lectures through computer-based simulations (MATLAB) of different components of a communication system. Students analyze how variations in system parameters affect overall system performance. Assessment of these sessions is carried out through tests and the submission of laboratory reports. The tutoring system includes a weekly schedule of two hours of individual tutorials, which is published on GLOBAL CLASSROOM. In addition, prior to each continuous assessment midterm exam, a group tutorial session is held to address questions related to the contents of the corresponding assessment.
