Communication Theory (2nd course, 1st. semester)

The student will acquire knowledge about the principles of contemporary telecommunication systems. With an integrating and systemic character, the student acquires the ability to analyze and design complete telecommunication systems according to the fundamental quality parameters and requirements. He/She will also be able to evaluate the pros and cons of different technological alternatives. (PO a, c, e, h, j, k) The student will learn the fundamentals of digital communication techniques (linear, non linear, multicarrier and spread spectrum) and basic error correction techniques in digital communications. Also, the student will be capable of communicating efficiently in written and oral form, the procedure followed to solve problems of design of mobile communication systems. (PO g)

1. Introduction to telecommunication systems and digital communications: classification, basic concepts of networks, systems and services, regulation. 2. Linear modulation techniques: low-pass and band-pass PAM; bandwidth and noise analysis. 3. Phase and frequency modulation techniques: phase non linear modulation; frequency and continuous phase modulation. 4. Multipulse modulation: multicarrier modulation; spread spectrum modulation; bandwidth and noise analysis. 5. Error correction techniques. block codes; convolutional and trellis coding modulation (TCM). 6. Fixed communication systems: HFC networks, xDSL, PON. 7. Radio communication systems: terrestrial radiolinks, mobile communications, WLAN, Satellite Communications Systems. 8. Broadcasting Systems: DVB standards.

Two types of learning activities will be used: theory lectures and study cases. ECTS credits include the work to be carried out by the student either personally or in groups. THEORY LECTURES (4ECTS) Theory lectures are taught using the blackboard or other audiovisual media in order to illustrate some concepts. In these sessions the theoretical concepts will be illustrated with practical exercises. In these lectures the student will acquire the basic knowledge of the course. It is important to highlight that these sessions will require the initiative and participation from the student (some concepts will have to be studied personally with some indications, particular cases will have to be developed, ¿) (PO a, c, e, g, h, j, k) STUDY CASES (2 ECTS) In order for the student to acquire en integrated and systemic view of telecommunication systems, He/She will practice deeper, through personal work, in specific telecommunication systems. In these study cases the student will have to use the knowledge acquired in previous subjects, of a more specific character, about the different techniques and technologies that are applicable to telecommunication systems.
