摘要：
We propose a novel compensation method for frequency-selective I/Q Imbalance in OFDM receivers. The proposed algorithm allows simultaneous estimation of the I/Q imbalance and the channel, and can be used for all existing OFDM standards. Simulation results show that our method allows to compensate for extremely frequency-selective I/Q Imbalance on the reception of the first packet.
