Low-Complexity Soft-Decision Detection for Combating DFE Burst Errors in IM/DD Links
Kaiquan Wu, Gabriele Liga, Jamal Riani +1
The deployment of non-binary pulse amplitude modulation (PAM) and soft decision (SD)-forward error correction (FEC) in future intensity-modulation (IM)/direct-detection (DD) links…
Temporal Properties of Enumerative Shaping: Autocorrelation and Energy Dispersion Index
Yunus Can Gültekin, Kaiquan Wu, Alex Alvarado
We study the effective SNR behavior of various enumerative amplitude shaping algorithms. We show that their relative behavior can be explained via the temporal autocorrelation func…
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…
Exponentially-Weighted Energy Dispersion Index for the Nonlinear Interference Analysis of Finite-Blocklength Shaping
Kaiquan Wu, Gabriele Liga, Yunus Can Gültekin +1
A metric called exponentially-weighted energy dispersion index (EEDI) is proposed to explain the blocklength-dependent effective signal-to-noise ratio (SNR) in probabilistically sh…
