Ukubunjwa komlaza wesiginali

UZhi Zhang et al. kusukela eSikoleni Sokuxhumana Nobunjiniyela Bolwazi, Inyuvesi Yesayensi Yezogesi Nobuchwepheshe Yase-China yaklama uhlelo lwezinkanyezi lwe-Reshaping Chaotic encryption (CSCEn) olunokulawulwa kokusatshalaliswa kwezibalo, njengoba kuboniswe ku-FIG. 2. Okokuqala, ukulandelana kwezimpawu zokuguquguquka kwe-orthogonal amplitude (QAM) kwahlukaniswa kwaba ukulandelana okuncane okumbalwa, futhi ukubunjwa 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.
