ECTS - University of Pisa
The course deals in general with the different techniques for the transmission of information in digital form. Starting form the basics of Information Theory about source and channel encoding, it gives a working knowledge of the main narrowband and wideband digital signalling techniques (including multicarrier and spread spectrum) as well as of channel coding. This is also complemented by notions about the main impairments deriving from signal transmission over the physical media (mainly the wireless radio channel), together with the main detection and signal processing techniques that are used to counteract such phenomena.
The student who successfully completes the course will have the ability to understand the main communication standards for the delivery of digital information in the Future Internet. It will master digital signalling and formatting for wireless and wired communications in 3G and 4G cellular networks and in ADSL, and will have a fundamental knowledge about the issues of digital encoding of information and exploitation of communication resources like energy and bandwidth.
