Orthogonal frequency division multiplexing (OFDM) is now well known as a powefull
modulation scheme for high data rate wireless communications owing to its many advantages,
notably its high spectral efficiency, mitigation of intersymbol interference (ISI), robustness to
frequency selective fading environment, as well as the feasibility of low cost transceivers [1].
On the other hand multiple input multiple output (MIMO) systems can also be efficiently
used in order to increase diversity and improve performance of wireless systems [2] [3] [4].
Moreover, as OFDM allows a frequency selectivechannel to be considered as flat on each
subcarrier, MIMO and OFDM techniques can be well combined. Therefore, MIMO-ODFM
systems are now largely considered in thenew generation of standards for wireless
transmissions, such as 3GPP/LTE [5] [6].
