N2 - Stokes space modulation format recognition (Stokes MFR) is a
blind method enabling digital coherent receivers to infer modulation format
information directly from a received polarization-division-multiplexed
signal. A crucial part of the Stokes MFR is a clustering algorithm, which
largely influences the performance of the detection process, particularly at
low signal-to-noise ratios. This paper reports on an extensive study of six
different clustering algorithms: k-means, expectation maximization,
density-based DBSCAN and OPTICS, spectral clustering and maximum
likelihood clustering, used for discriminating between dual polarization:
BPSK, QPSK, 8-PSK, 8-QAM, and 16-QAM. We determine essential
performance metrics for each clustering algorithm and modulation format
under test: minimum required signal-to-noise ratio, detection accuracy and
algorithm complexity.
