| Title: | Low-complexity and phase noise tolerant carrier phase estimation for dual-polarization 16-QAM systems | Authors: | Gao, Y Lau, APT Yan, S Lu, C |
Issue Date: | 24-Oct-2011 | Source: | Optics express, 24 Oct. 2011, v. 19, no. 22, p. 21717-21729 | Abstract: | 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 200Gb/s DP-16-QAM system demonstrate similar linewidth tolerance to the best feedforward CPE reported to date while the computational complexity is at least three times lower compared with other simplified feed-forward CPE techniques. | Keywords: | Estimation Maximum likelihood estimation Polarization Quadrature amplitude modulation |
