Data-Aided OSNR Estimation for QPSK and 16-QAM Coherent Optical System

Data-Aided OSNR Estimation for QPSK and 16-QAM Coherent Optical System

We propose an optical signal-to-noise ratio (OSNR) estimation technique using self-equalized complementary Golay sequences for both QPSK and 16-QAM coherent optical systems. The training sequences have complementary spectra, which enable accurate channel estimation and equalization, and have length-...
