Nonlinearity Compensation for Coherent Optical Satellite Communications
Stella Civelli, Luca Potì, Enrico Forestieri +1
Optical satellite uplinks rely on high-power optical amplifiers (HPOAs) to overcome free-space attenuation and enable long-distance transmission. However, at high power levels, fib…
Soft-Decoding Reverse Reconciliation in Discrete-Modulation CV-QKD
Marco Origlia, Emanuele Parente, Marco Secondini
In continuous-variable quantum key distribution, information reconciliation is required to extract a shared secret key from correlated random variables obtained through the quantum…
Sequence-Selection-Based Constellation Shaping for Nonlinear Channels
Stella Civelli, Enrico Forestieri, Marco Secondini
Probabilistic shaping is a pragmatic approach to improve the performance of coherent optical fiber communication systems. In the nonlinear regime, the advantages offered by probabi…
On the Nonlinear Shaping Gain with Probabilistic Shaping and Carrier Phase Recovery
Stella Civelli, Emanuele Parente, Enrico Forestieri +1
The performance of different probabilistic amplitude shaping (PAS) techniques in the nonlinear regime is investigated, highlighting its dependence on the PAS block length and the i…
New Lower Bounds on the Capacity of Optical Fiber Channels via Optimized Shaping and Detection
Marco Secondini, Stella Civelli, Enrico Forestieri +1
Constellation shaping is a practical and effective technique to improve the performance and the rate adaptivity of optical communication systems. In principle, it could also be use…
Coupled-Channel Enhanced SSFM for Digital Backpropagation in WDM Systems
S. Civelli, E. Forestieri, A. Lotsmanov +2
A novel technique for digital backpropagation (DBP) in wavelength-division multiplexing systems is introduced and shown, by simulations, to outperform existing DBP techniques for a…
