In communication systems, Multiple-Input Multiple-Output (MIMO) plays a major role because of its high performance. In MIMO systems, multiple antennas are used in both transmitter and receiver to improve the communication performance, whereas the Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation method. MIMO-OFDM is commonly used for communication systems due to its high transmission rates and robustness against multipath fading. In MIMO-OFDM, channel estimation plays a major role and channel estimation is the estimation of the transmitted signal bits using the corresponding received signal bits.
