A method and apparatus is provided for transceiving an information signal in an orthogonal frequency division multiplexed (OFDM) communication system that uses a plurality of radio frequency subcarriers modulated with the information signal and transceives the modulated plurality of radio frequency subcarriers through first and second antennas at a transmitter and first and second antennas at a receiver. The method includes the steps of providing first and second copies of the modulated plurality of radio frequency subcarriers that are transmitted from the transmitter to the receiver, phase rotating the first copy of the modulated plurality of radio frequency carriers with a subcarrier dependent phase rotation and summing the first rotated copy of the plurality of radio frequency subcarriers with the second copy of the modulated plurality of radio frequency carriers.
