ABSTRACT:
Disclosed is an apparatus and method for encoding/decoding a space time block code in a mobile communication system using a multiple input multiple output scheme. In a transmitter employing a plurality of transmit antennas in the mobile communication system, if a signal to be transmitted is input, the transmit signal is pre-encoded according to a preset coding scheme, the pre-encoded signal is space-time mapped according to a number of the transmit antennas to employ a preset space time block coding scheme, and the space-time mapped signal is transmitted through the transmit antennas by applying the preset space time block coding scheme to the space-time mapped signal.
