Abstract :
The Digital Communications modules supplement the networks and electronics modules in the training of wireless networks (WiFi, WIMAX), TV broadcasting systems (DVB-T, DVB-S) and cellular systems (GSM, GPRS, UMTS). This teaching applies the concepts acquired in 1st year to the field of telecommunications. At the end of the course, students should be able to identify the basic functions fulfilled in all the modems used in the communications systems. This course approaches the following points: digital modulations (PAM, PSK, QAM, FSK), architecture of the receivers in the case of AWGN channels.The approach of this course is voluntarily theoretical. The comprehension of the theoretical aspects of digital communications constitutes the appreciation of an engineer compared to a high-level technician.
