Course Description:	The Digital Communications Systems will allow the students to get a very deep knowledge about the different problems that arise during the transmissions and how those are overcome. They will get good knowledge about the signaling how it is performed in GSM systems. They will get good knowledge about the signal spectrum and the limitation into the power transmitted in different frequency bands. They will study the GSM system in particular with all its generations and PSTN. They will acquire good knowledge about source coding, channel coding and multiplexing of different transmission as well about the digital modulation schemes.
Course Objectives:	To acquire good knowledge about Telecommunication and the systems where digital communication is applied. The issues and problems that those systems holds and the modulation techniques and protocols used in such systems.

BASIC CONCEPTS OF THE COURSE

1	The study of the physical layer and the digital data transmissions.
2	The study of A/D conversion or the channel encoding.
3	The channel coding and different algorithms applied for error detection and corrections.
4	Channel capacity, the bandwidth, the Path Loss coefficient and frequency and distance.
5	PST, GSM system and signaling.
6	Power Spectrum Density evaluation and the masks.
