35114 - Communications Systems (2nd Cycle)

Academic Year 2018/2019

  • Docente: Davide Dardari
  • Credits: 6
  • SSD: ING-INF/03
  • Language: Italian

Learning outcomes

At the end of the course, students will acquire the fundamentals of digital communication systems, with reference to terrestrial and satellite wireless links. In particular, students will be able to design wireless systems working in the presence of propagation and power efficiency constraints by applying proper system-level techniques. Moreover, they will be able to analyze third and fourth generation cellular systems (UMTS/LTE).

Course contents

  • Introduction to wireless systems.
  • Elements of detection, estimation and digital transmission theory.
  • The wireless channel.  Performance evaluation in the presence of co-channel interference and fading. Countermeasures techniques (adaptive equalization, diversity). 
  • Introduction to multiple antenna systems (multiple-input multiple-output, MIMO).
  • Cellular communications: frequency reuse, multiple access techniques, spread spectrum techniques, multi-carrier modulation (OFDM).
  • Third and fourth generation cellular systems.
    Seminars on GSM, UMTS, LTE, and DVB-T standards.
