On Optimum Enumerative Sphere Shaping Blocklength at Different Symbol Rates for the Nonlinear Fiber Channel
Yunus Can Gültekin, Olga Vassilieva, Inwoong Kim +3
We show that a 0.9 dB SNR improvement can be obtained via short-blocklength enumerative sphere shaping for single-span transmission at 56 GBd. This gain vanishes for higher symbol…
4D Geometric Shell Shaping with Applications to 400ZR
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Geometric shell shaping is introduced and evaluated for reach increase and nonlinearity tolerance in terms of MI against PM-16QAM and PS-PM-16QAM in a 400ZR compatible transmission…
Introducing 4D Geometric Shell Shaping for Mitigating Nonlinear Interference Noise
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Four dimensional geometric shell shaping (4D-GSS) is introduced as an approach for closing the nonlinearity-caused shaping gap. This format is designed at the spectral efficiency o…
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…
