Briefly, an apparatus and method to transmit data stream by using a multiple-input-multiple-output (MIMO) transmitters receivers system. The MIMO transmitters receivers system may include a coding mode selector to select a coding mode of each orthogonal frequency division multiplexing (OFDM) sub-carrier symbol of a first and second sub-carriers of a data stream according to a feedback data packet having coding information of the OFDM subcarrier symbol. The coding mode may be selected from a diversity coding mode and a multiplexing coding mode.
