The student who successfully completes the course will gain a solid introduction about the basic principles of both digital and analog communication systems, exemplified by an overview on the architecture and main characteristics of a few up-to-date wireless standards as well. By virtue of the first part of the course unit, the student will tackle the characterization of analog and digital communication signals and systems. She or he will acquire ability on handling specific issues, such as A/D conversion techniques, transmitter and receiver design, receiver sensitivity to thermal noise, and performance comparison of various modulation formats. In the second part, the above theoretical concepts will make the students grasp the underlying essential about commonly employed wireless systems, such as terrestrial digital video broadcasting (DVB-T), digital audio broadcasting (DAB), wireless local area network (IEEE 802.11 g/a/n), satellite-based Globalstar radio mobile system and GPS.
In the oral exam, the student will be asked to demonstrate her/his knowledge of the material presented within the course, namely concerning the basic principles of digital and analog communication systems and main characteristics of the wireless standards.

In the first part, a typical baseband digital communication system is introduced. Then, the characterization of passband signals and systems together with the sensitivity of the receiver to the thermal noise enable the discussion of the main digital and analog modulation schemes followed by the performance comparison in terms of bit error rate (BER) and output signal-to-noise-ratio (SNR), respectively. The second part is devoted to a few significant up-to-date wireless standards. DAB and DVB-T are illustrated. The architecture of a WLAN based on the IEEE 802.11 g/a/n standards is addressed. The main segments of the radio mobile Globalstar system are analyzed by defining the structure of the satellite transponder and the multiuser signaling based on DS/SS CDMA. Finally, the GPS satellite positioning system is introduced, discussing the signal structure, the main techniques adopted to evaluate position and reference timing, the errors affecting performance and the available accuracy.
