The objective of the project is to study different aspects related to the lower layers of communications systems, giving special emphasis to the analysis, design and demonstration of advanced transceivers over the radio channel. The different communication aspects that are taken into account can be described as: modulation/coding, single and multi-antenna communications, microwave engineering, cooperative transmission, medium access control, radio resource management, scheduling, mobility and network quality of service.
