Modulation-Independent Polarization-Division Demultiplexing Without CMA Drawbacks
Technology Benefits
Polarization-division demultiplexing without prior knowledge of modulation format
Technology Application
Optical communications
Detailed Technology Description
ICA determines an inverse transformation matrix to separate a mixed polarization signal. Because ICA requires two statistically independent polarizations, it avoids the problem associated with CMA of polarization convergence. With statistical independence and a tensor-based algorithm, the inventors have demonstrated polarization demultiplexing using ICA without any extra parameters on an experimental quadrature phase shift (QPSK) system and simulated QPSK and 16-QAM systems.
