Aim

This course considers the latest technology development in wireless communications, including 5G and LTE systems. These systems are high performing and represent "state-of-the-art" in many aspects. A central part of this course is to give detailed knowledge of the communication methods that are used in down-link and in up-link, respectively, that make these high performance increases possible. This course also includes trends for future system solutions. The aim of this course is to give good knowledge concerning principles, concepts, functioning, performance and limitations for such systems for mobile communications.
