Improved Frequency Domain Equalizer with Carrier Phase and Frequency Offset Estimation and Transmitter IQ Skew Mitigation

We propose an improved frequency domain equalizer (FDE) which can effectively estimate and compensate carrier phase and frequency offset and mitigate the transtimtter IQ skew in coherent optical communications, and significantly reduce the computational complexity of time domain equalizer (TDE).
