The analysis of the error statistics in a 5 x 40 Gbit/s fibre link with hybrid amplification
Skidin, A.; Redyuk, A.; Shtyrina, O.; Fedoruk, M.; Shafarenko, Alex (2011-09)We quantify the error statistics and patterning effects in a 5 × 40 Gbit/s WDM RZ-OOK SMF/DCF fibre link using hybrid Raman/EDFA amplification. By extensive use of a numerical model, we determine how the error statistics ... -
Efficient weakly-constrained codes for mitigation of patterning effects in digital communications
Shafarenko, A.; Fedoruk, M.; Skidin, A.; Turitsyn, S.K. (2009)We propose specific modulation block codes for weakly-constrained coding and demonstrate that their performance is close to the theoretical limit. We also show that when such codes are used for the mitigation of patterning ... -
The error statistics analysis of the QPSK-modulated signal in the high-rate optical link
Redyuk, A.; Skidin, A.; Fedoruk, M.; Shafarenko, Alex (2013-06-01)A model of an optical fibre communication line operating at 80 Gb/s with QPSK modulation format is studied numerically. The error statistics and patterning effects are analyzed and nonlinear transmission impairments of the ... -
Weakly-Constrained Codes for Suppression of Patterning Effects in Digital Communications
Shafarenko, A.; Skidin, A.; Turitsyn, S.K. (2010-10)We propose weakly-constrained stream and block codes with tunable pattern-dependent statistics and demonstrate that the block code capacity at large block sizes is close to the the prediction obtained from a simple Markov ...
