چکیده
We propose a novel carrier phase estimator based on two-stage Viterbi-Viterbi and QPSK partitioning for 16-QAM. Simulation shows that the proposed algorithm is highly tolerant to laser linewidth with a reduced cycle slip probability.

A Simple Improvement to the Viterbi and Viterbi Monomial-Based Phase Estimators
It is well known that the Viterbi and Viterbi MonomialBased Phase Estimator, which includes the M Power Estimator, performs poorly for cross QAM signals. However, it is shown here that by allowing the power of the monomial to be negative, much improved performance can be realized at medium to high signalto-noise ratios (SNR). Monte Carlo simulations are used to demonstrate the efficacy of this ...
متن کاملComprehensive study of CD compensation and carrier phase estimation in optical communication systems influenced by equalization enhanced phase noise
The performance of long-haul coherent optical fiber transmission system is significantly affected by the equalization enhanced phase noise (EEPN), due to the interaction between the electronic dispersion compensation (EDC) and the laser phase noise. In this paper, we present a comprehensive study on different chromatic dispersion (CD) compensation and carrier phase recovery (CPR) approaches, in...
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملLow-complexity and phase noise tolerant carrier phase estimation for dual-polarization 16-QAM systems.
A low-complexity feed-forward carrier phase estimation (CPE) technique is presented for dual-polarization (DP)-16-QAM transmission systems. By combining QPSK partitioning, maximum likelihood (ML) detection and phase offset estimation between signals in different polarizations, simulation and experimental results for a 200 Gb/s DP-16-QAM system demonstrate similar linewidth tolerance to the best...
متن کاملStudy of EEPN mitigation using modified RF pilot and Viterbi-Viterbi based phase noise compensation.
We propose--as a modification of the optical (RF) pilot scheme--a balanced phase modulation between two polarizations of the optical signal in order to generate correlated equalization enhanced phase noise (EEPN) contributions in the two polarizations. The method is applicable for n-level PSK system. The EEPN can be compensated, the carrier phase extracted and the nPSK signal regenerated by com...
