Adaptive Electrical Signal Post-Processing in Optical Communication Systems
Sun, Yi.; Shafarenko, A.; Adams, R.G.; Davey, N.; Slater, B.; Bhamber, R.; Boscolo, S.; Turitsyn, S.K. (INSTICC (Inst. Syst. Technologies Information Control and Communication), 2008)Improving bit error rates in optical communication systems is a difficult and important problem. The error correction must take place at high speed and be extremely accurate. We show the feasibility of using hardware ... -
Correcting Errors in Optical Data Transmission Using Neural Networks
Hunt, S.; Sun, Yi.; Shafarenko, A.; Adams, R.G.; Davey, N.; Slater, B.; Bhamber, R.; Boscolo, S.; Turitsyn, S.K. (2010)Optical data communication systems are prone to a variety of processes that modify the transmitted signal, and contribute errors in the determination of 1s from 0s. This is a difficult, and commercially important, problem ... -
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 ... -
Information theory analysis of skewed coding for suppresion of pattern-dependant errors in digital communications
Shafarenko, A.; Turitsyn, S.K.; Turitsyn, K.S. (2007)We present information-theory analysis of the tradeoff between bit-error rate improvement and the data-rate loss using skewed channel coding to suppress pattern-dependent errors in digital communications. Without loss of ... -
Reduction of nonlinear intrachannel effects by channel asymmetry in transmission lines with strong bit overlapping
Shapiro, E.G.; Fedoruk, M.; Turitsyn, S.K.; Shafarenko, A. (2003-10) -
Skewed coding for suppression of pattern-dependent errors
Shafarenko, A.; Turitsyn, K.S.; Turitsyn, S.K. (Institute of Electrical and Electronics Engineers (IEEE), 2005)We present information theory analysis of the trade-off between BER improvement and the data rate loss using skewed channel coding to suppress pattern-dependent errors. -
Using Simple Neural Networks to Correct Errors in Optical Data Transmission.
Hunt, S.; Sun, Yi; Shafarenko, A.; Davey, N.; Boscolo, S.; Turitsyn, S.K. (De Montfort University, 2008)We have demonstrated the applicability of neural-network-based systems to the problem of reducing the effects of signal distortion, and shown that such a system has the potential to reduce the bit-error-rate in 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 ...
