The performance of different probabilistic amplitude sha** (PAS) techniques in the
nonlinear regime is investigated, highlighting its dependence on the PAS block length and …

Constellation sha** is a practical and effective technique to improve the performance and
the rate adaptivity of optical communication systems. In principle, it could also be used to …

The interaction between carrier phase recovery and probabilistic amplitude sha** (PAS)
in the nonlinear regime is investigated. We show that, for sufficiently high signal-to-noise …

Regular perturbation is applied to the Manakov equation and motivates a generalized
correlated phase-and-additive noise model for wavelength-division multiplexing over dual …

We experimentally demonstrated a photoelectric nonlinear compensation scheme of optical
phase conjugation (OPC) with complex-valued deep neural network (CVDNN) to mitigate …

Generalized mutual information (GMI) is used to compute achievable rates for fading

Joint detection and decoding (JDD) achieves rates based on information theory but is too
complex to implement for many channels with memory or nonlinearities. Successive …

This work proposes a novel low-complexity digital backpropagation (DBP) method, with the
goal of optimizing the trade-off between backpropagation accuracy and complexity. The …
