Band-ESS: Streaming Enumerative Coding with Applications to Probabilistic Shaping
Yunus Can Gültekin, Frans M. J. Willems, Alex Alvarado
Probabilistic amplitude shaping (PAS) is on track to become the de facto coded modulation standard for communication systems aiming to operate close to channel capacity at high tra…
Mitigating Nonlinear Interference by Limiting Energy Variations in Sphere Shaping
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Band-trellis enumerative sphere shaping is proposed to decrease the energy variations in channel input sequences. Against sphere shaping, 0.74 dB SNR gain and up to 9% increase in…
List-encoding CCDM: A Nonlinearity-tolerant Shaper Aided by Energy Dispersion Index
Kaiquan Wu, Gabriele Liga, Alireza Sheikh +3
Recently, a metric called energy dispersion index (EDI) was proposed to indicate the nonlinear interference (NLI) induced by correlated symbols during optical transmission. In this…
On Kurtosis-limited Enumerative Sphere Shaping for Reach Increase in Single-span Systems
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
The effect of decreasing the kurtosis of channel inputs is investigated for the first time with an algorithmic shaping implementation. No significant gains in decoding performance…
Orthogonal Time Frequency Space Modulation: A Discrete Zak Transform Approach
Franz Lampel, Alex Alvarado, Frans M. J. Willems
In orthogonal time frequency space (OTFS) modulation, information-carrying symbols reside in the delay-Doppler (DD) domain. By operating in the DD domain, an appealing property for…
