5G SYSTEMS

Second cycle degree in ICT FOR INTERNET AND MULTIMEDIA

Campus: PADOVA

Language: English

Teaching period: First Semester

Lecturer: STEFANO TOMASIN

Number of ECTS credits allocated: 6


Syllabus
Prerequisites: Basics of communications, networking and signal processing techniques.
Examination methods: Writing of a short report on an assigned topic. Discussion of the report and questions on the contents of the course.
Course unit contents: The course will include two parts:

1. A general description of forthcoming 5G communication standard, and
2. A detailed analysis of two key technologies: OFDM and MIMO

For the first part we will see the evolution of mobile wireless systems up to the 4th generation, the objectives of 5G systems, and then we will have an overview phyisical layer (filterbanks, massive MIMO), medium access (mm-wave, OFDMA) and network solutions (small cells/cloud networking).

The second part will focus on the the orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO) systems. Various issues will be addressed, including design of OFDM systems, channel estimation, resource allocation. About MIMO, concepts of diversity and multiplexing will be investigated. Decoding techniques for MIMO systems will be discussed, including sphere decoder, interference cancellation. Channel models currently used in standard development for MIMO systems will also be presented. Lastly, multiuser MIMO in cellular system will be studied.
