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 okuvumelana nezimo ngobunkimbinkimbi obuphansi futhi luthuthukise ukusebenza kokuthumela nokwamukela amasignali, kodwa futhi lunikeze ukuvikeleka okwanele ukumelana nokuhlasela okuvela kuyunithi yenethiwekhi ye-optical engekho emthethweni (ONU), ngokungangabazeki kuyoba nethuba elihle lokufaka isicelo esizayo.
