Ukubunjwa komlaza wesiginali

UZhi Zhang et al. kusukela eSikoleni Sokuxhumana Nobunjiniyela Bolwazi, iNyuvesi Yesayensi Yezobuchwepheshe Nobuchwepheshe yaseChina yaklama uhlelo lwe-constellation Reshaping chaotic encryption (CSCEn) olukwazi ukulawuleka ukusatshalaliswa kwezibalo, njengoba kuboniswe ku-FIG 2. Okokuqala, ukulandelana kwezimpawu ze-orthogonal amplitude (QAM) kwahlukaniswa. ekulandeleni 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 nokuhlaselwa okuvela kuyunithi yenethiwekhi ye-optical engekho emthethweni (I-ONU), ngokungangabazeki kuzoba nethuba elihle lokufaka isicelo esikhathini esizayo.
