Publikováno v: 2021 IEEE Photonics Conference (IPC).

In this paper, we propose a joint estimation and compensation algorithm to mitigate the transmitter IQ imbalance and laser phase noise effects in coherent optical systems using DSP algorithms. The effectiveness of the proposed method is validated by
