Systems and methods for performing channel equalization in a communication system are presented. More particularly, embodiments of the disclosed method and apparatus are directed toward systems and methods for performing channel equalization in an OFDM system. One example of a method of negating the effects of IQ imbalance can include the operations of transmitting a channel estimation string across a channel. The channel estimation string comprises a plurality of known channel estimation symbols. The method further includes logically inverting predetermined symbols within the known channel estimation string; transmitting a second channel estimation string across the channel, the second channel estimation string including the logically inverted predetermined symbols; and estimating the IQ image noise based on received first and second channel estimation symbols.
