Optimized Sub-Rate Sampling in 80Gbaud DP-64QAM Coherent Optical Receivers
2021 7th International Conference on Computer and Communications (ICCC)（2021）
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 simula...
