In-Band Estimation of Optical Signal-to-Noise Ratio From Equalized Signals in Digital Coherent Receivers
TL;DR: A novel method of in-band estimation of optical signal-to-noise ratio (OSNR) using a digital coherent receiver, where OSNR is determined from second- and fourth-order statistical moments of equalized signals in any modulation format is proposed.
Proceedings ArticleDOI
Blind equalization and carrier-phase recovery in QPSK coherent optical receivers based on modified constant-modulus algorithm
Saifuddin Faruk,Kazuro Kikuchi +1 more
TL;DR: A fully-blind scheme for equalization and carrier-phase recovery in QPSK coherent optical receivers, which is based on the modified CMA, is proposed and experimentally verified.
Proceedings ArticleDOI
Modified CMA based blind equalization and carrier-phase recovery in PDM-QPSK coherent optical receivers
TL;DR: A novel equalization and carrier-phase recovery algorithm, both based on modified constant-modulus algorithm (CMA), is proposed for polarization-division multiplexed quadrature phase-shift keying (PDM-QPSK) systems.
Proceedings ArticleDOI
Least radial distance based carrier phase recovery for 16-QAM coherent optical systems
TL;DR: In this article, the least radial distance based carrier-phase recovering method for 16-QAM coherent optical systems was proposed and demonstrated, which has less than 2dB SNR penalty when laser linewidth-symbol-duration-product product Δv Ts ≅ 1 × 10-4 range.
