In this paper, the authors study the performance of a REconfigurable Multiple-Input Multiple-Output (RE-MIMO) system in spatially correlated frequency-selective fading channels. In particular, they propose to use a RE-MIMO system to overcome the Inter Symbol Interference (ISI) problem caused by multipath propagation. In the proposed system, they use a 3-dimensional coding scheme to obtain the same diversity order as in MIMOOFDM systems over frequency-selective channels, and achieving better bit error rate performance by using directive reconfigurable antennas. To demonstrate the superiority of the proposed system, they compare the performance of the RE-MIMO with MIMO-OFDM system over frequency-selective channels.
