Optical fiber kutaurirana
Irene Estebanez et al. kubva kuThe Institute of Physics uye Complex Systems muSpain yakashandisa yakanyanyisa Kudzidza Machine (ELM) algorithm kuti iwanezve data yakagamuchirwa ye optical fiber transmission system, sezvinoratidzwa mumufananidzo 1. Ongororo yekuedza inoitwa mu 100km optical fiber transmission system uchishandisa 56GBand. ina-level pulse amplitude modulation (PAM-4) uye kuona zvakananga. Vatsvagiri vakaunza kunonoka kuchengetedza algorithm (TDRC) sechirongwa chekuenzanisa, uye yakaratidza kuti kutora ELM algorithm kunogona kurerutsa masisitimu, kubvisa simba shoma rekumhanya kwekombuta kunokonzerwa nekunonoka kwenguva, uye kuve nekuita kwakafanana kwekuita sekutora TDRC chirongwa [1. ]. Iyo hurongwa inotsigira kukanganisa-isina decoding kana iyo optical sign-to-noise ratio (OSNR) yakakura kupfuura 31dB, uye ine zvirinani kuita kukanganisa pane iyo KK yekugamuchira chirongwa chakaitwa nekunze kwedhijitari Signal processing (DSP).
