    Ulawulo lwemposiso kwiNkqubo yoNxibelelwano lweDatha

    Ixesha lokuposa: Aug-02-2022

    Molweni Bafundi, Kweli nqaku siza kufunda ukuba yintoni Ulawulo lwemposiso kunye nokuhlelwa kokulawula iimpazamo.

    Kwinkqubo yokuhanjiswa kwedatha, ngenxa yempembelelo yengxolo kwitshaneli, i-wave waveform inokuphazamiseka xa idluliselwa kumamkeli, okukhokelela kwiimpazamo zolwazi. Ukuze uhlangabezane neemfuno ezilindelekileyo zezi mpazamo, ulawulo lwempazamo luyafuneka. Umgaqo wolawulo lwempazamo kukuba emva kokuba i-K bits yolwazi idluliselwe, kukho i-R ye-bits engafunekiyo kwixabiso lesitokhwe. Ulwazi olufunyenwe ngummkeli lusebenzisa i-algorithm edibeneyo, kwaye umphumo uthelekiswa nesiphumo somthumeli. impazamo. Ukuba umamkeli uyazi ukuba kukho impazamo, kodwa akazi ukuba yintoni na impazamo, aze acele ukuthunyelwa kwakhona kumthumeli, eli qhinga libizwa ngokuba lubhaqo lwempazamo; ukuba umamkeli uyazi ukuba kukho impazamo kwaye uyazi ukuba yintoni na impazamo, eli qhinga libizelwa ukulungiswa kwempazamo.

     

    (2) Ukuhlelwa kokulawulwa kweempazamo

    Kukho iindidi ezimbini zolawulo lwemposiso: iimpazamo ezincinci kunye neempazamo zesakhelo. Impazamo encinci yimpazamo encinci, u-1 uba ngu-0, u-0 uba ngu-1; kukho iimpazamo ezintathu ezinokwenzeka kwisakhelo: ilahleko, uphinda-phindo, kunye ne-out-of-order. Ukuba kukho impazamo ehambelanayo, ngoko kufuneka sicele isisombululo kwi-data link layer ukuya kumncedisi onikezelwe ngumsebenzi womnatha. Umaleko wekhonkco ledatha ubonelela ngemisebenzi emithathu esisiseko kumaleko womnatha:

     

    1. Akukho siqinisekiso kwaye akukho nkonzo yoqhagamshelwano.

    2. Qinisekisa ukuba akukho nkonzo yoqhagamshelwano.

    3. Iinkonzo ezijoliswe kwikhonkco eziqinisekisiweyo.

     

    Oku ngasentla yingcaciso yolwazi "Ulawulo lwempazamo" oluziswe yi-Shenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zonxibelelwano eziveliswe yikhava yenkampani: Iindidi zeemodyuli: iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl.

    I-ONUudidi: EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.

    OLTiklasi: Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwanoOLT, njl.

    Iimveliso zemodyuli ezingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuweQhagamshelana nathi kulo naluphi na uhlobo lombuzo.

    Ulawulo lwemposiso kuluhlu lwekhonkco lwedatha, yintoni ulawulo lwempazamo kuthungelwano, ulawulo lwempazamo kuluhlu lwedatha oluchaziweyo, ulawulo lwempazamo kwinqaku ledatha yedatha pdf
