Fundamentals of communications

Course objectives

Goal of this course is to describe the behaviour and evaluate the performance of the main components (e.g., functional blocks) constituting the analogue and digital communication systems and the packet-switched data networks. Expected results It is expected that the attending students will acquire the basic notions about architectures and related performance of both analogue and digital the TLC systems. A good underground of analogue and digital signal processing is demanded. Required background A good background on Signal Processing in the continuous-time and discrete-time domains is required.
