Ukubunjwa komlaza wesiginali

UZhi Zhang et al.kusukela eSikoleni Sokuxhumana Nobunjiniyela Bolwazi, iNyuvesi Yesayensi Yezobuchwepheshe Nobuchwepheshe yaseChina yaklama uhlelo lwezinkanyezi lwe-Reshaping Chaotic encryption (CSCEn) olukwazi ukulawuleka ukusatshalaliswa kwezibalo, njengoba kuboniswe ku-FIG 2. Okokuqala, ukulandelana kwezimpawu ze-orthogonal amplitude (QAM) kwahlukaniswa. ekulandelaneni okuncane okuningana, kanye nokubunjwa okungenzeka (PS) kwenziwa ngokusekelwe olwazini lwezibalo (SI) (ngokushintsha indawo yesifunda sezinkanyezi).Ngemva kwalokho, ukulandelana kwe-SI kwabhalwa ngekhodi futhi kwabethelwa ezigabeni zesignali yesiphithiphithi kusetshenziswa i-algorithm yokusabalalisa ukhiye.I-SI ikhishwe ekugcineni kokwamukela ukuze kubuyiselwe isignali yasekuqaleni [2].Abacwaningi bathumele ngempumelelo isignali ye-ps-16-qam ebethelwe ngefayibha yemodi eyodwa ejwayelekile (SSMF) engu-25km.Ngoba lolu hlelo alukwazi nje ukubona ukuthunyelwa okuguquguqukayo okuyinkimbinkimbi ephansi futhi kuthuthukise ukusebenza kokuthumela nokwamukela amasignali, kodwa futhi kunikeze ukuvikeleka okwanele ukumelana nokuhlasela okuvela kuyunithi yenethiwekhi ye-optical engekho emthethweni (I-ONU), ngokungangabazeki kuzoba nethuba elihle lokufaka isicelo esikhathini esizayo.
