Abstract
The sampling rate of Analog-to-Digital Converters (ADCs) is a key technology for high speed optical links. It is difficult for DSP to recover the clock and data due to the impact of ADCs’ sub-sampling. For DP-64QAM coherent optical communication system, anti-aliasing and optimal sampling are used to realize the sub-sampling of ADCs. The sampling rate and bit error rate can be reduced in the simulation experiment.
