Knowledge
The student who successfully completes the course will be able to demonstrate a solid knowledge of the main concpets related to analog and digital communication signals and systems. He or she will acquire ability in dealing with modulation and demodulation techniques, evaluation of the main figures of merit of a communication system, analysis of the impact of noise and interference in a receiver, statistical characterization of the transmission medium, digital communication over bandwidth constraint channels and the main multiple access methods to ensure channel sharing among several simultaneously active users. The student will also be aware of recently deployed communications systems, such as the wireless local area network, wireless metropolitan area network and 3G cellular systems.
Assessment criteria of knowledge
During the written exam (2 hours), the student is asked to solve two or three exercises in order to demonstrate the ability to put into practice the basic concepts of analog and digital communication systems illustrated throughout the course.
During the oral exam, the student will be assessed on his/her ability in discussing the main course contents with competence, critical awareness and propriety of expression.
Methods:
- Final oral exam
- Final written exam
Further information:
The final test is composed by a written exam followed by an oral exam. In general, both each part contributes 50% to the definition of the final grade.

Syllabus
The course covers the main analog modulation techniques, including amplitude modulation (AM,DSB,SSB) and frequency modulation (FM) with emphasis on their spectral and power efficiencies. It then illustrates the pulse code modulation (PCM) for the conversion of an time-continuous analog signal into a bit sequence. The course also approaches the main issues related to digital transmissions over the bandwidth constrained AWGN or Rayleigh channel, illustrating the optimum design of the transmit and receive filters to counteract the effects of thermal noise and intersymbol interference, the channel equalization process and the optimum detection strategies for data recovery. Lastly, the concept of multiple access is introduced and some recently deployed communications systems based on CDMA or OFDM/OFDMA are presented and discussed.
