Abstract
We study the impact of stressors such as phase slips on the performance of LDPC codes with differentially encoded coherent DP-QPSK, comparing classical soft-decision decoding and iterative (turbo) differential decoding. We find that turbo decoding shows improved baseline performance but suffers from severely reduced phase slip resilience.
