Systems and methods are described for dynamic switching techniques for space-time coding/decoding based on channel status information for a MIMO-OFDM system. The system and method for dynamic switching of space-time coding mode include a determining step for determining a space-time coding mode based on feedback information by a transmitter; a mapping step for mapping the determined coding mode to a corresponding coder so that a number of sets symbol streams corresponding to respective transmit antennas are generated after coding a modulated symbol sequence for desired coding; and a feedback step for periodically feeding used coding mode information back to a receiver via a forward control channel.
