Abstract

A complex adaptive equalizer using a least-mean-square (LMS) algorithm is proposed to mitigate the effect of nonlinear interference induced by cross-phase modulation in wavelength-division multiplexing (WDM) coherent optical systems. We show the effect of nonlinear interference is equivalent to slow time-varying intersymbol interference. Simulations of dual-polarization 16 quadrature amplitude modulation (QAM) WDM systems are conducted to test the effectiveness of our proposed compensation method. The consequences show that significant improvement in system performance can be achieved by using the adaptive LMS equalization method.
