Mandatory requirements: Exam and Matlab project. It is also possible to pass the course (with grade 1) without taking the exam, by actively attending the learning events, doing exercises, and completing the project work.

Additional literature study/research project needed as a post-graduate course.

The assessment is primarily based on the exam which, together with the quality of the project work, are targeted at measuring the knowledge gained in the core contents. Also active participation in learning sessions has a positive effect on the grading. Grade 3 can be reached by showing good command of the core contents. Fluent/profound understanding of core contents, along with elements of complementary knowledge, are required for grades 4 and 5. With minor gaps in the core knowledge, grades 2 and 1 are possible. With significant gaps in the core knowledge or insufficient project work, the student is not able to pass the course. It is also possible to pass the course (with grade 1) without taking the exam, by actively attending the learning events and completing the project work.

Learning Outcomes

The course focuses on multicarrier (OFDM, OFDMA, SC-FDMA, FBMC, DMT) and multiantenna/MIMO digital communication techniques, which are central ingredients in all advanced communication system developments including mobile communication systems (LTE, LTE-A, 5G), WLAN/WiFi, terrestrial TV transmission (DVB-T), and digital subscriber line modems (ADSL, VDSL, etc). After completing the course, a student has in-depth knowledge about multicarrier and multiantenna based digital communication techniques and their applications in current and emerging broadband digital communication systems and networks. She/he is able to construct a model for an OFDM transmission link and explain its core functionalities. He/she has also good understanding of different multiantenna transmission schemes and their applicability and benefits in different radio communication scenarios.

Prerequisites

Course Mandatory/Advisable Description
ELT-41308 Communication Theory Mandatory    
ELT-43008 Digital Communication Advisable    

Additional information about prerequisites
In summary: General understanding of linear systems and filters, elements of radio communication links, spectrum concept, and basic digital modulation techniques are important background knowledge. If you have passed earlier versions of the pre-requisite courses (ELT-41307, ELT-43007), they are certainly ok as well.
