Practical Implementation of Sequence Selection for Nonlinear Probabilistic Shaping
Stella Civelli, Enrico Forestieri, Marco Secondini
We propose two novel techniques to implement sequence selection (SS) for fiber nonlinearity mitigation, demonstrating a nonlinear shaping gain of 0.24 bits/s/Hz, just 0.1 bits/s/Hz…
Tailored Shaping, Improved Detection, Simpler Backpropagation: the Road to Nonlinearity Mitigation
Marco Secondini, Stella Civelli, Enrico Forestieri
Several strategies for nonlinearity mitigation based on signal processing at the transmitter and/or receiver side are analyzed and their effectiveness is discussed. Improved capaci…
A Sequence Selection Bound for the Capacity of the Nonlinear Fiber Channel
Stella Civelli, Enrico Forestieri, Alexey Lotsmanov +2
A novel technique to optimize the input distribution and compute a lower bound for the capacity of the nonlinear optical fiber channel is proposed. The technique improves previous…
Interplay of Probabilistic Shaping and Carrier Phase Recovery for Nonlinearity Mitigation
Stella Civelli, Enrico Forestieri, Marco Secondini
The interaction between carrier phase recovery and probabilistic amplitude shaping (PAS) in the nonlinear regime is investigated. We show that, for sufficiently high signal-to-nois…
Hierarchical Distribution Matching: a Versatile Tool for Probabilistic Shaping
Stella Civelli, Marco Secondini
The hierarchical distribution matching (Hi-DM) approach for probabilistic shaping is described. The potential of Hi-DM in terms of trade-off between performance,complexity, and mem…
Improved Detection Strategies for Nonlinear Frequency-Division Multiplexing
Stella Civelli, Enrico Forestieri, Marco Secondini
Two novel detection strategies for nonlinear Fourier transform-based transmission schemes are proposed. We show, through numerical simulations, that both strategies achieve a good…
