In this letter, we analyze three different carrier phase estimation approaches for coherent optical systems based on multi-subcarrier modulation, comparing them in terms of both performance and complexity. Averaging the estimated values on the subcar

We analyze the impact of finite resolution of DAC and ADC on the performance of coherent-detection optical communication systems using probabilistically-shaped 64-QAM constellations. We show that no substantial additional penalty is incurred with res

In this letter, a novel two-stage digital feed forward carrier recovery algorithm for 64-ary quadrature amplitude modulation (QAM) is proposed and analyzed. Due to the absence of any feedback loop, the approach shows a high tolerance toward laser pha
