Cost-Gain Analysis of Sequence Selection for Nonlinearity Mitigation
arXiv:2411.02004
Abstract
We propose a low-complexity sign-dependent metric for sequence selection and study the nonlinear shaping gain achievable for a given computational cost, establishing a benchmark for future research. Small gains are obtained with feasible complexity. Higher gains are achievable in principle, but with high complexity or a more sophisticated metric.
