Ukuxhumana kwe-fiber optical
U-Irene Estebanez et al.kusukela ku-Institute of Physics and Complex Systems eSpain isebenzise i-algorithm ye-Extensive Learning Machine (ELM) ukuze iphinde ithole idatha etholiwe yesistimu yokudlulisa i-fiber optical, njengoba kuboniswe kuMfanekiso 1. Ucwaningo lokuhlola lwenziwa ku-100km optical fiber transmission system kusetshenziswa i-56GBand. i-pulse amplitude modulation yezinga amane (PAM-4) kanye nokutholwa okuqondile.Abacwaningi bethule i-algorithm yokulibaziseka (i-TDRC) njengesikimu sokuqhathanisa, futhi bafakazela ukuthi ukwamukela i-algorithm ye-ELM kungenza kube lula ukucushwa kwesistimu, kuqede umthelela olinganiselwe wejubane lekhompyutha elibangelwa ukubambezeleka kwesikhathi, futhi kube nokusebenza okucishe kufane okufanayo nokwemukela uhlelo lwe-TDRC [1 ].Isikimu sisekela ukuqoshwa okungenamaphutha uma isilinganiso se-optical signal-to-noise ratio (OSNR) sikhulu kuno-31dB, futhi sinokusebenza kwephutha okungcono kunohlelo lokwamukela lwe-KK olusetshenziswa ngokungaxhunyiwe ku-inthanethi Kwesiginali yedijithali (DSP).
