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.
