Unxibelelwano lwefiber optical
U-Irene Estebanez et al. ukusuka kwi-Institute of Physics kunye ne-Complex Systems eSpain isebenzise i-algorithm yokuFunda ngokugqithisileyo (ELM) ukubuyisela idatha efunyenweyo yenkqubo yokudlulisa i-fiber optical, njengoko kubonisiwe kuMfanekiso 1. Uphando lovavanyo lwenziwa kwi-100km inkqubo yokuhambisa i-fiber optical usebenzisa i-56GBand. I-modulation ye-pulse amplitude yezinga elinesine (PAM-4) kunye nokufumanisa ngokuthe ngqo. Abaphandi bazise i-algorithm yokulibaziseka (i-TDRC) njengesikimu sokuthelekisa, kwaye bangqina ukuba ukwamkela i-algorithm ye-ELM kunokwenza lula ulungelelwaniso lwenkqubo, kuphelise impembelelo enyiniweyo yesantya sekhompyuter esibangelwa kukulibaziseka kwexesha, kwaye ibe phantse ukusebenza ngendlela efanayo njengokwamkela iskimu se-TDRC [1 ]. Iskimu sixhasa i-decoding-free-decoding xa i-optical signal-to-noise ratio (OSNR) inkulu kune-31dB, kwaye inentsebenzo yempazamo engcono kune-KK yokufumana iskimu ephunyezwe yi-offline digital Signal processing (DSP).
