Because of the enormous capacity upsurge a MIMO systems offer; such systems gained a lot of interest in mobile communication research. One indispensable problem of the wireless channel is fading, which occurs as the signal follows multiple paths between transmitter and receiver antennas. Fading can be mitigated by diversity, which means that the information is transmitted not only once but several times, hoping that at least one of the replicas will not undergo severe fading. There are various coding methods, a main issue in all these schemes is the exploitation of redundancy to achieve high reliability, and high spectral efficiency and high performance gain for MIMO-OFDM systems earlier.
