Cooperative Communications (389.121)

Past course at Vienna University of Technology, summer term 2011

Lecturer: Thomas Zemen and Nicolai Czink

Aim of course

In this course, we cover the fundamentals of cooperative communications over wireless channels. We will discuss information-theoretic and signal processing aspects, as well as channel models for cooperative communications. Finally, we exemplify the theory by discussing the designs of practical cooperative communication schemes and applications.

Subject of course

Second and third generation cellular communication systems (GSM, UMTS, LTE) require direct communication links between the base stations and the mobile terminals. Hence, sufficient link quality indoor, in street canyons and for highly mobile users is still difficult to provide at all times. Relaying of a weak signal by means of another node can improve link quality and the overall network capacity. Furthermore a group of nodes can cooperatively form a virtual multiple-input multiple-output (MIMO) system, which allows directing the radio beam spatially in the best direction. Cooperative communication techniques could become a promising foundation for future communication systems. This course provides a basic introduction into this new and highly interesting field.
