Paper Abstract

In paper we present low-complexity feed-forward algorithm for digital signal processing in coherent optical 16QAM systems, employing adaptive filtering for decreasing linewidth phase noise of coherent laser. Simulations show performance that using dual polarization for 16 quadrature-amplitude modulation (QAM) transmission is possible for laser beat linewidths of ΔfTs = 0.3 ∙ 10-3 and ΔfTs = 7.9 ∙ 10-5 when soft-decision phase estimator is employed.
