The objectives of the course are 1) To address several key issues such as noise, bandwidth limitation, interference; and to investigate their effects on the performance of communication systems, through error probability analysis. 2) To analyze the different types of transmission media and their impairments. 3) To explore fundamental limits of communication systems, such as channel capacity. 4) To plan and analyze simple communication systems in terms of coverage and capacity. Related to the following: ) Specific objectives 1.- cognitive - Transmission concepts - Channel characterization and modelling. - Quality measurement in communication channels - Limits in Performance of physical channels. - Design and planning of communication systmes 2.- Instrumental - Programming with channel simulation software
Learning Outcomes
CB1: Students have demonstrated possession and understanding of knowledge in an area of study that builds on the foundation of general secondary education, and is usually at a level that, while relying on advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study. CB2: Students are able to apply their knowledge to their work or vocation in a professional manner and possess the competences usually demonstrated through the development and defence of arguments and problem solving within their field of study. ECRT1: Ability to learn and acquire autonomously the requisite new knowledge for design, development and utilization of telecommunication systems and services. 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. ECRT8: Ability to understand the mechanisms of electromagnetic and acoustic wave propagation and transmission, and their corresponding transmitting and receiving devices. RA1: Knowledge and Understanding. Knowledge and understanding of the general fundamentals of engineering, scientific and mathematical principles, as well as those of their branch or specialty, including some knowledge at the forefront of their field. RA2: Analysis. Graduates will be able to solve engineering problems through an analysis process, identifying the problem, recognising specifications, establishing different methods of resolution, selecting the most appropriate one and implementing it correctly. They must be able to use various methods and recognize the importance of social constraints, human health, safety, the environment, as well as commercial constraints. RA5: Applications. Graduates will have the ability to apply their knowledge and understanding to solve problems, conduct research, and design engineering devices or processes. These skills include knowledge, use and limitations of materials, computer models, process engineering, equipment, practical work, technical literature and information sources. They must be aware  of all the implications of engineering practice: ethical, environmental, commercial and industrial. RA6: Generic competences. Graduates will have the generic skills necessary for engineering practice, and which are widely applicable. First, to work effectively, both individually and as a team, as well as to communicate effectively. In addition, demonstrate awareness of the responsibility of engineering practice, social and environmental impact, and commitment to professional ethics, responsibility and standards of engineering practice. They must also have knowledge of business and project management practices, as well as risk management and control, and understand their limitations. Finally, have the capacity for continuous learning.

Learning activities and methodology
The course consists of the following elements: lectures, exercises, and computer exercises. LECTURES (2,5 ECTS) The ON LINE lectures provide the students with explanation of the core material in the course. EXERCISES (2.5 ECTS) In these sessions at the classroom, students will discuss problems which merge the different concepts together. LABORATORIES (1 ECTS) Some selected concepts will be discussed using the computer. Students may form small working groups.
