Enhanced Multicarrier Techniques for Professional Ad-Hoc and Cell-Based Communications

This document shortly summarizes the main concepts that will be presented in deliverable D6.2. The issue of coordinated beamforming design for distributed multi-user MIMO systems using FBMC/OQAM is investigated. New methods are developed to alleviate the dimensionality constraint imposed on the number of antennas in state-of-the art solutions. Both cases of full coordination and partial coordination are considered. Furthermore, solutions are also investigated for highly selective channels where other methods, which are based on the usual assumption of an approximatively flat channel across subcarriers, fail to provide satisfactory results. Finally, the related issue of preamble-based MIMO channel estimation is investigated for synchronized and unsynchronized scenarios.
