Not Accessible

Your library or personal account may give you access

Abstract

We propose a novel method of OSNR estimation in Nyquist-WDM transmission systems based on the measurement of statistical moments of equalized signals in the digital coherent receiver. Its effectiveness is verified with computer simulations.
