“…An effective form of PDL compensation without channel knowledge at the transmitter was analyzed using DGD predistortion. It has to be noted that transmitter-sided PMD leads to a higher nonlinear penalty due to the higher peak-to-average power ratio [8]. This penalty can be effectively eliminated using optically uncompensated links [9].…”

“…In most channels, the global minimum of the CMA cost function is close to the MMSE solution, while the LMS achieves MMSE 1041-1135/$26.00 © 2010 IEEE performance for a sufficient number of training symbols [4]. The performance boundaries for PDL will be derived for a flat-fading channel with lumped noise at the receiver given by (8) where is the 2 1 received signal vector, is the number of polarizations, is the 2 2 channel matrix, is the 2 1 transmit signal vector, is the noise vector, and the symbol energy per polarization. The signal-to-noise ratio (SNR) on the th polarization can be approximated from the zero-forcing (ZF) equalizer solution given by [5] ( 9) where is the total SNR of the two polarizations in front of the equalizer.…”

Abstract-In this paper, we outline the design of signal processing (DSP) algorithms with blind estimation for 100-G coherent optical polarization-diversity receivers in single-carrier systems. As main degrading optical propagation effects, we considered chromatic dispersion (CD), polarization-mode dispersion (PMD), polarization-dependent loss (PDL), and cross-phase modulation (XPM). In the context of this work, we developed algorithms to increase the robustness of the single DSP receiver modules against the aforesaid propagation effects. In particular, we first present a new and fast algorithm to perform blind adaptive CD compensation through frequency-domain equalization. This low complexity equalizer component inherits a highly precise estimation of residual dispersion independent from previous or subsequent blocks. Next, we introduce an original dispersion-tolerant timing recovery and illustrate the derivation of blind polarization demultiplexing, capable to operate also in condition of high PDL. At last, we propose an XPM-mitigating carrier phase recovery as an extension of the standard Viterbi-Viterbi algorithm.

“…In particular polarization-multiplexed return-to-zero differential quadrature phase shift keying (POLMUX-RZ-DQPSK), combined with coherent detection and digital signal processing, has been considered as a promising candidate [1]. This solution is particularly interesting as it is compatible with a 50-GHz wavelength grid and can tolerate the inter-channel nonlinear impairments generated from co-propagating 10.7-Gb/s and 43-Gb/s channels [2,3]. However, one of the most significant advantages of a coherent receiver combined with digital signal processing is the capability to compensate fully for chromatic dispersion (CD) [4] and to a large extend for polarization mode dispersion in the electrical domain [1].…”
