Igishushanyo cya 6-6 nigishushanyo mbonera cya sisitemu isanzwe yohereza ibimenyetso bya baseband. Igizwe ahanini no kohereza muyunguruzi (umuyoboro wibimenyetso byerekana umuyoboro), umuyoboro, kwakira akayunguruzo nicyemezo cyo gutoranya. Kugirango tumenye neza imikorere yizewe kandi itunganijwe ya sisitemu, hagomba no kubaho sisitemu ihuza.
Imikorere ya buri gasanduku mumashusho hamwe nuburyo bufatika bwo kohereza ibimenyetso byasobanuwe gutya:
(1) Imiyoboro yerekana ibimenyetso (kohereza akayunguruzo). Igikorwa cyayo ni ugutanga ibimenyetso bya baseband byerekana imiyoboro ikwiranye numuyoboro. Kuberako ibyinjijwe muri rusange ari kode yoherejwe ikorwa na kodegisi ya kodegisi, ihuriro ryibanze rihuza ubusanzwe ni impiswi y'urukiramende, kandi spekure yayo ni nini cyane, ntabwo ifasha kwanduza. Akayunguruzo koherejwe gakoreshwa muguhuza ibimenyetso byinjira byinjira no guhindura kode yohereza muri baseband signal signal ya flame ikwiranye numuyoboro.
(2) Umuyoboro. Nuburyo butuma ibimenyetso bya baseband byanyura, mubisanzwe umuyoboro winsinga, nkumugozi uhindagurika, umugozi wa coaxial, nibindi. Ibiranga imiyoboro yumurongo mubisanzwe ntabwo byujuje ibisabwa byo kwanduza ubusa, bityo bizatera kugoreka ya ihererekanyabubasha. Mubyongeyeho, umuyoboro utangiza urusaku n (t) ukeka ko ari urusaku rwera rwa Gaussiya rufite uburyo bwa zeru.
(3) Kwakira akayunguruzo. Byakoreshejwe mukwakira ibimenyetso, gushungura urusaku rwumuyoboro nizindi mbogamizi zishoboka, kuringaniza imiyoboro yumurongo, no gukora ibisohoka baseband waveform bifasha gufata ibyemezo.
(4) Icyemezo cyo gutoranya. Munsi yinyuma yibiranga bidashimishije hamwe n urusaku, ibisohoka byamazi yo kuyungurura byakirwa mugihe cyagenwe (bigenzurwa nigihe gito pulse) kugirango agarure cyangwa asubize ibimenyetso bya baseband.
(5) Igihe cyagenwe no gukuramo icyarimwe. Ibihe bito byigihe cyakoreshejwe muguhitamo byakuwe mubimenyetso byakiriwe n'umuzunguruko wa syncronous, kandi ubunyangamugayo bwibihe bizagira ingaruka kumyanzuro ifatika.
Iyi ni ShenzhenHDV Phoelectron Ikoranabuhanga Ltd kugirango ikuzanire kubyerekeye "Ibigize sisitemu yohereza ibimenyetso bya sisitemu ya baseband", twizere kugufasha, na ShenzhenHDV Phoelectron Technology Ltd yongeyehoONUurukurikirane, urukurikirane rw'ibihe,OLTurukurikirane, ariko kandi rutange urutonde rwamasomo, nka: Itumanaho rya optique module, itumanaho ryitumanaho ryitumanaho, imiyoboro ya optique, itumanaho rya optique, module ya fibre optique, module ya fibre optique, nibindi, birashobora gutanga serivise nziza ijyanye nibyifuzo bitandukanye byabakoresha. , ikaze uruzinduko rwawe.
