Optical fiber kev sib txuas lus
Irene Estebanez et al.los ntawm Lub Tsev Haujlwm ntawm Physics thiab Complex Systems hauv Spain tau siv lub tshuab kev kawm huab cua (ELM) algorithm kom rov qab tau cov ntaub ntawv tau txais ntawm cov khoom siv fiber ntau kis tau tus mob, raws li qhia hauv daim duab 1. Kev tshawb fawb tau ua tiav hauv 100km optical fiber kis tau tus mob siv 56GBand plaub-theem mem tes amplitude modulation (PAM-4) thiab nrhiav tau ncaj qha.Cov kws tshawb fawb tau qhia txog kev ncua sijhawm cia (TDRC) raws li kev sib piv, thiab tau ua pov thawj tias kev siv ELM algorithm tuaj yeem ua kom yooj yim rau kev teeb tsa, tshem tawm cov kev txwv tsis pub muaj kev cuam tshuam los ntawm kev ncua sij hawm, thiab muaj ze li qhov kev ua tau zoo ib yam li kev siv TDRC scheme [1 ].Cov tswv yim txhawb nqa kev txiav txim tsis raug yuam kev thaum lub teeb liab-rau-lub suab sib piv (OSNR) ntau dua 31dB, thiab muaj kev ua yuam kev zoo dua li KK txais cov tswv yim siv los ntawm offline digital Signal processing (DSP).
