Igishushanyo cya 6-6 ni igishushanyo mbonera cya sisitemu isanzwe yohereza ibimenyetso bya baseband. Igizwe ahanini na filteri yohereza (umuyoboro wa signal yerekana umuyoboro), umuyoboro, akayunguruzo, hamwe nicyitegererezo. Kugirango tumenye imikorere yizewe kandi itunganijwe ya sisitemu, hagomba no kubaho sisitemu yo guhuza.
Imikorere ya buri gice mumashusho hamwe nuburyo bufatika bwo kohereza ibimenyetso byasobanuwe muri make kuburyo bukurikira:
(1) Umuyoboro werekana icyambere (akayunguruzo). Igikorwa cyayo ni ugukora baseband signal waveform ikwiranye numuyoboro. Kuberako ibyinjijwe muri rusange ari ihererekanyabubasha ryakozwe na kode yubwoko bwa kodegisi, ihuriro ryibanze rihuza ubusanzwe ni impiswi y'urukiramende, kandi spécran yayo ni nini cyane, ntabwo ifasha kwanduza. Akayunguruzo koherejwe gakoreshwa muguhuza ibimenyetso byinjiza no guhindura kode yoherejwe muri baseband signal waveform ikwiranye numuyoboro.
(2) Umuyoboro. Nibikoresho byemerera ibimenyetso bya baseband kunyuramo, mubisanzwe umuyoboro winsinga, nkumugozi uhindagurika, umugozi wa coaxial, nibindi. Ibiranga umuyoboro wumuyoboro mubisanzwe ntabwo byujuje ibyerekeranye no kwanduza ubusa, bityo imiyoboro yohereza kugoreka. Byongeye kandi, urusaku n (T) rwinjijwe mumuyoboro, kandi hafatwa ko ari urusaku rwera rwo muri Gaussiya rufite agaciro ka zeru.
.
(4) Uwatoranije icyitegererezo. Nugushushanya no kumenya ibyasohotse kumurongo wakira muyunguruzi mugihe cyagenwe (kugenzurwa na biti ya pulse pulse) kugirango ugarure cyangwa wongere ibimenyetso bya baseband munsi yibiranga kwanduza bidashimishije n urusaku.
. Ukuri kwigihe ntarengwa bizagira ingaruka kubisubizo byicyemezo.
Nibigize sisitemu ya sisitemu ya baseband yoherejwe na sisitemu yazanwe na Shenzhen HDV Phoelectron Technology Co., Ltd. Nizere ko iyi ngingo ishobora kugufasha kongera ubumenyi. Usibye iyi ngingo niba ushaka ibikoresho byiza bya fibre itumanaho ibikoresho bya sosiyete ushobora gutekerezaibyerekeye twe.
Shenzhen HDV ifoto yamashanyarazi ikorana buhanga, Ltd ahanini ikora ibicuruzwa byitumanaho. Kugeza ubu, ibikoresho byakozwe bitwikiriyeUrukurikirane rwa ONU, icyiciro cya optique, Urukurikirane rwa OLT, naurukurikirane. Turashobora gutanga serivisi yihariye kubintu bitandukanye.
