# Regular Perturbation and Achievable Rates of Space-Division Multiplexed Optical Channels

@article{Gmez2021RegularPA, title={Regular Perturbation and Achievable Rates of Space-Division Multiplexed Optical Channels}, author={Francisco Javier Garc{\'i}a G{\'o}mez and Gerhard Kramer}, journal={2021 17th International Symposium on Wireless Communication Systems (ISWCS)}, year={2021}, pages={1-5} }

Regular perturbation is applied to space-division multiplexing (SDM) on optical fibers and motivates a correlated rotation-and-additive noise (CRAN) model. For <tex>$S$</tex> spatial modes, or 2 <tex>$S$</tex> complex-alphabet channels, the model has 4 <tex>$S$</tex>(<tex>$S$</tex> + 1) hidden independent real Gauss-Markov processes, of which 2 <tex>$S$</tex> model phase noise, 2 <tex>$S$</tex>(2 <tex>$S$</tex> - 1) model spatial mode rotation, and 4 <tex>$S$</tex> model additive noise… Expand
