Estimation Uncertainties in the Optical Signal-to-Noise Ratio Network Optimization

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In this work, we investigate the effects of estimation uncertainties in the optimization of the optical signal-to-noise ratio (OSNR) at the wavelength division multiplexing (WDM) optical networks.
