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…
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…
