Course Objectives

The aim of this course is to provide a solid overview of the major 4G technologies and functionalities. We start by explaining 3.5G schemes such as AMC, H-ARQ and power control, then discuss OFDM, OFDMA, and SC-FDMA. Finally we concentrate on MIMO and multiuser detection. Our objective is to train a student in such a way that she/he is able to design, evaluate or use new radio access technologies and functionalities regardless of the actual system context. This is particularly important nowadays, when various telecom systems are utilizing the very same fundamental concepts.

Pre-requisites
