International audienceA low-complexity feedforward CFO compensation method is proposed and numerically validated for both square and cross M-QAM modulation in optical coherent systems. The proposed method is further compared to state-of-the-art methods and its effectiveness is experimentally verified in a 10-GBaud 16-QAM system
