(1) Kunobva kukodha uye decoding
Mabasa maviri akakosha: rimwe nderekuvandudza kushanda kwekufambiswa kwemashoko, ndiko kuti, kuburikidza nerumwe rudzi rwekumanikidza coding tekinoroji kuyedza kudzikisa huwandu hwezviratidzo kuderedza chiyero chechiratidzo. Yechipiri ndeyekupedzisa analog/digital (A/D) shanduko, kureva kuti, kana sosi yeruzivo ichipa chiratidzo cheanalog, sosi encoder inoishandura kuita chiratidzo chedhijitari kuti iwane kufambiswa kwedhijitari yechiratidzo cheanalog.
(2) Channel coding uye decoding
Basa: Kudzora kukanganisa. Chiratidzo chedhijitari chichakanganiswa neruzha uye zvimwe zvikanganiso muhurongwa hwekutapurirana. Kuti uderedze zvikanganiso, iyo chiteshi encoder uye chinofambiswa ruzivo chinhu chinowedzera zvinhu zvekudzivirira (supervisory elements) zvinoenderana nemimwe mitemo kugadzira iyo inonzi "anti-interference coding". Iyo chiteshi decoder painogashira yekupedzisira inodhirodha zvinoenderana nemitemo inoenderana inverse kuwana kana kugadzirisa zvikanganiso uye kugadzirisa kuvimbika kweiyo nzira yekutaurirana.
(3) Encryption uye decryption
Kuti uve nechokwadi chekuchengetedzwa kweruzivo rwakafambiswa, kutevedzana kwedhijitari kunokanganiswa nekutapurirana, ndiko kuti, password inowedzerwa, iyi nzira inonzi encryption. Kudzoreredza meseji yepakutanga ndeye decryption.
(4) Digital modulation uye demodulation
Digital modulation: Iyo frequency spectrum yedhijitari baseband siginecha inofambiswa kune yakakwirira frequency kuumba bhendi yekutaurirana siginecha yakakodzera kutapurirana muchiteshi. Pakupera kwekugamuchira, iyo yedhijitari baseband siginecha inogona kudzoreredzwa neinobatana demodulation kana isina-yakabatana demodulation.
(5) Kuwiriranisa
Synchronization: Iko kuchengetedza masaini kumagumo ese ekugamuchira uye kugamuchira mukufambirana neimwe nguva nenguva, uye chinhu chinodiwa kuti uve nechokwadi chekurongeka, kwakaringana uye kwakavimbika basa redhijitari yekutaurirana system.
Iyi iShenzhen HDV phoelectron Technology Ltd. kuti ikuunze nezve "communication system model" chinyorwa, tariro yekukubatsira, Shenzhen HDV phoelectron Technology Ltd. inyanzvi yekugadzira yevagadziri vemidziyo yekutaurirana, zvigadzirwa zvekambani zvinopisa zvekutaurirana ndezvi:ONUseries, transceiver series,OLTdzakatevedzana, asiwo kugadzirwa kwemodule dzakatevedzana, dzakadai se: Communication optical module, optical communication module, network optical module, communication optical module, optical fiber module, Ethernet optical fiber module, nezvimwewo, inogona kupa iyo inoenderana mhando sevhisi yevashandisi vakasiyana. ' zvinoda, gamuchira kushanya kwako.
