We propose a decision-aided joint compensation scheme of channel distortion and transmitter IQ imbalance for coherent optical orthogonal frequency-division-multiplexed (CO-OFDM) system. In this letter, we compare this decision-aided method with Gram-Schmidt orthogonalization procedure (GSOP) and another pilot-assisted (PA) method through computer simulation. It is demonstrated that our decision-aided method is superior to the other two methods.
