Abstract:
Disclosed are an system and method for compensation of I/Q imbalance in a beamforming OFDM system. The system comprises: a TX beamformer configured at a transmitter end of the beamforming OFDM system; a noise whitener configured at a receiver end of the beamforming OFDM system; and a RX MMSE configured at the receiver end of the beamforming OFDM system. At least one of the TX beamformer, the noise whitener and the RX MMSE receiver, or any combination thereof are capable of jointly processing a carrier and its image subcarrier to compensate the I/Q imbalance in the beamforming system.
