Wireless communications
5.00 credits
30.0 h + 30.0 h
Main themes
This course is one of the last courses in the telecommunication cursus. LELEC2796 deals with the PHY layer of wireless communication systems, along three axes : radio channels, signal processing techniques and communication standards.
Learning outcomes

At the end of this learning unit, the student is able to :

1 With respect to the AA referring system defined for the Master in Electrical Engineering, the course contributes to the develoopment, mastery and assessment of the following skills :
  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.2, AA2.4
  • AA3.1
  • AA4.1, AA4.2, AA4.4
  • AA5.2, AA5.3, AA5.6
  • AA6.1, AA6.3
At the end of the course, the student will be able to :
  • Define concepts enabling to fully characterize radio channels (narrow- and wideband, as well multi-antenna channels)
  • Explain through analytical models and Matlab simulations the impact of the propagation channel and co-channel interference on system performance
  • Describe and compare various multiple access techniques (TDMA/FDMA/CDMA)
  • Explain, via mathematical representations, and analyze receive techniques (Rake receiver, joint detection, OFDM, SIMO/MISO/MIMO)
  • Describe the radio interface of wireless communication standards (GSM, UMTS, IS95/UTRA, 3G-LTE), together with the underlying concepts
  • Present (written report and oral presentation) the results achieved within a group project, consisting in the Matlab implementation of a wireless system in a real-world channel
  • Introduction to wireless communication systems
  • Random signals, modulations and detection
  • Mobile transmission channels
  • GSM standard
  • Multiple access techniques
  • CDMA, Rake reception and diversity
  • UTRA and WCDMA standards
  • Multi-carrier and OFDM systems
  • Multi-antenna channels and systems
  • MIMO techniques
  • LTE and LTE-A standards
Teaching methods
The course is organized as
  • 13 lectures
  • 5 to 6 exercise sessions
  • a group project
Evaluation methods
Regarding the course, the oral (and/or written) evaluation is individual (no book/notes allowed) and based on clearly announced objectives (see above).
The evaluation of the project is based on the submission of a written report and an oral presentation by the group; the acquired project grade holds for all sessions (January and August).
The final grade is obtained by combining the grades of the exam and the project as follows
  •     if the 2 marks are equal to or higher than 7/20, the project is worth 1/3 of the overall mark;
  •     if one of the two marks is strictly less than 7/20, the overall mark is the minimum of the two marks.
Other information
It is advized to follow LELEC2796 during Master 2.
