Learning outcomes
This class is the follow-up of Electrical Communications L.
The course intends providing the basic tools for the understanding
of the fundamental principles governing digital communications
systems. The focus will be on multiplexing and multiaccess
techniques, digital modulation theory, error correction coding
schemes, and optimum reception in linear channels. The course will
be completed with the overview of two communication systems: the
cellular UMTS system and the DVB-H sstem for digital video
broadcasting to handheld devices.
