OSNR monitoring for PM-QPSK systems in presence of fiber nonlinearities for digital coherent receivers

We propose OSNR monitoring for PM-QPSK systems in presence of fiber nonlinearities by characterizing the nonlinearity-induced amplitude noise correlation among neighboring symbols and incorporating it into a typical OSNR estimator based on received signal distributions.
