Minimum distances of LDPC codes in 5G standard
V. R. Danilko, I. Yu. Mogilnykh, Ya. A. Tikhomolov
We propose several approaches for bounding the minim\-um distances of the family of quasi-cyclic LDPC codes in the 5G NR standard. In particular, we show that the high-rate [9984,…

ML-assisted Subband Learned Digital Backpropagation for Nonlinearity Compensation in Wideband Optical Systems
Evgeny Shevelev, Oleg Sidelnikov, Vitaly Danilko +2
Digital backpropagation (DBP) is one of the most effective techniques for compensating nonlinear distortions in coherent optical fiber communication systems. However, its practical…

CNN-Assisted Particle Swarm Optimization of a Perturbation-Based Model for Nonlinearity Compensation in Optical Transmission Systems
Alexey Redyuk, Evgeny Shevelev, Vitaly Danilko +1
Nonlinear signal distortions are one of the primary factors limiting the capacity and reach of optical transmission systems. Currently, several approaches exist for compensating no…
