Abstract
Abstract-In digital coherent optical receivers for various polarization-multiplexed high-order modulation formats such as BPSK、QPSK、8PSK and 16QAM signals, we propose and investigate a blind modulation format recognition method using the Chinese Restaurant Process, a kind of Dirichlet model, which is based on the observation of samples in Stokes space. The recognition rates of different number of data points under different optical signal-to-noise ratios (OSNRs) are investigated in detail for four modulation formats. In addition, the recognition characteristics of the proposed method are compared with other format recognition methods in Stokes space. It is shown that the approach has a better performance with higher recognition rates, particularly under a lower OSNR.
