Recent advances in MIMO wireless systems

• In the next years, one of the most significant technological developments that will lead to the new broadband wireless generation is the communication via Multiple-Input Multiple-Output (MIMO) systems. MIMO systems are known to provide an increase of the maximum rate, reliability and coverage of current wireless communications, without additional bandwidth or transmit power. For these reasons, one of the research lines at the iTEAM research Institute is focused on this kind of wireless systems. This paper presents an overview of MIMO wireless techniques, highlighting the aspects of them where our research is mainly concentrated. Especially, the problems of efficient detection in point to point MIMO systems and beamforming in coordinated MU-MIMO systems are discussed. Finally, some solutions to these problems that have been carried out at the iTEAM are addressed.
