Isgaarsiinta fiber indhaha
Irene Estebanez iyo al.oo ka socda Machadka Fiisigiska iyo Nidaamyada Isku-dhafka ah ee Spain waxay adeegsadeen Mashiinka Waxbarasho ee xad-dhaafka ah (ELM) algorithm si ay u soo ceshadaan xogta la helay ee nidaamka gudbinta fiber indhaha, sida ku cad sawirka 1. Cilmi-baaris tijaabo ah ayaa lagu fuliyaa 100km nidaamka gudbinta fiber indhaha iyadoo la isticmaalayo 56GBand afar-heer garaaca garaaca garaaca (PAM-4) iyo ogaanshaha tooska ah.Cilmi baadhayaashu waxay soo bandhigeen algorithm dib udhigista (TDRC) qaab isbarbardhig ah, waxayna cadeeyeen in qaadashada ELM algorithm ay sii fududayn karto qaabaynta nidaamka, baabi'inta saamaynta xaddidan ee xawaaraha xisaabinta ee uu sababay daahitaanka wakhtiga, oo ay leeyihiin ku dhawaad ​​​​wax qabad la mid ah qaadashada nidaamka TDRC [1] ].Nidaamku waxa uu taageerayaa codaynta khalad la'aanta ah marka saamiga isha-ilaa-bulshada (OSNR) uu ka weyn yahay 31dB, oo uu leeyahay hawl-qabad khalad ah oo ka wanaagsan nidaamka helitaanka KK ee lagu hirgeliyay hab-samaynta Signal Digital Digital (DSP).
