Abstract :
A training sequence which realizes frame synchronization, frequency offset estimation and channel estimation simultaneously at the initial capturing stage is proposed and verified in a 32Gbaud DP-16QAM system. Experiment shows that it tolerates various linear distortions, such as CD, PMD and PDL, and avoids the singularity problem.
