Abstract

The paper presents a training sequence and an algorithm used for polarization demultiplexing in polarization division multiplexing coherent optical transmission system. The method can perform polarization demultiplex correctly and receiver is not required to synchronize with training sequence. Frequency offset can also be estimated with the training sequence.
