Viterbi-Viterbi Carrier Phase Estimation for Multi-Ring <inline-formula><tex-math notation="LaTeX">$M$</tex-math></inline-formula>-APSK With Wiener Carrier Phase Noise and Its Performance

High-order modulations are currently widely used in optical communications to increase the data rate. However, due to the existence of laser phase noise, the performance of high-order modulated systems will be greatly degraded. Therefore, phase estimation (PE) methods and laser linewidth tolerance a...
