This paper proposes a parametric network that benefits from the system knowledge and jointly compensates for the transmitter in-phase/quadrature imbalance, carrier frequency offset, and laser phase noise in coherent optical systems. The approach uses an original training technique that increases its experimentally validated effectiveness. For the considered setup, the performance of the network reaches the 3 rd Generation Partnership Project threshold of 17.5% Error Vector Magnitude for 4-QAM communications.
