Iyoubushobozi bwo koherezay'umuyoboro wumubiri urenze icyifuzo cyikimenyetso kimwe, umuyoboro urashobora gusangirwa nibimenyetso byinshi.Kurugero, umurongo wumurongo wa sisitemu ya terefone ubusanzwe ufite ibimenyetso ibihumbi n'ibihumbi byoherejwe kuri fibre optique. Multiplexing nubuhanga bukemura uburyo bwo gukoresha umuyoboro wohereza ibimenyetso byinshi icyarimwe. Ikigamijwe ni ugukoresha byuzuye umurongo wa frequency cyangwa igihe cyumutungo wumuyoboro no kunoza imikoreshereze yumuyoboro.
Harihouburyo bubiri busanzwe bwo kwerekana ibimenyetso: kugabana inshuro nyinshi (FDM) no kugabana umwanya kugwiza (TDM) Kugabana igihe kugwiza mubisanzwe bikoreshwa muguhuza ibimenyetso bya digitale. Kugabana inshuro nyinshi gukoreshwa cyane cyane kugwiza ibimenyetso bya analogue ariko birashobora no gukoreshwa kubimenyetso bya digitale. Iki gice kizaganira ku ihame no gushyira mu bikorwa FDM.
Kugabana inshuro nyinshi Kugwizani uburyo bwinshi bwo kugabanya imiyoboro ukurikije inshuro. Muri FDM, umurongo wumurongo wumuyoboro ugabanijwemo ubwinshi bwimigozi yumurongo (sub-imiyoboro) idahuza. Buri muyoboro wibimenyetso ufata imwe mungingo zinyuranye, kandi imirongo idakoreshwa (imirongo irinda) igomba kubikwa hagati yimiyoboro kugirango hirindwe ibimenyetso. Ku iherezo ryakira, umurongo ukwiye wa bande-utunguruzo utandukanya ibimenyetso byinshi kandi ugarura ibimenyetso bisabwa.
Igishushanyo gikurikira kirerekanaihame ryo guhagarika igishushanyo cya sisitemu yo kugabana inshuro nyinshi. Ku ihererekanyabubasha, buri kimenyetso cyijwi rya baseband kibanza kunyuzwa mumashanyarazi make (LPF) kugirango ugabanye inshuro ndende ya buri kimenyetso. Hanyuma, buri muyoboro wibimenyetso uhindurwamo inshuro zitandukanye zitwara ibintu, kuburyo buri muyoboro wibimenyetso wimurirwa kumurongo wacyo, hanyuma ugahuzwa hanyuma woherezwa kumuyoboro wohereza. Urukurikirane rwa band-pass muyunguruzi hamwe na centre yumurongo utandukanye kumpera yakira ikoreshwa mugutandukanya ibimenyetso byahinduwe. Nyuma yo kumanurwa, ibimenyetso bya baseband bihuye na buri muyoboro byagaruwe.
Mu rwego rwo gukumirakwivangahagati y'ibimenyetso byegeranye, inshuro zitwara F zigomba guhitamo_ c1, f_ c2, ···, f_ Cn kugirango umurongo runaka wizamu ubike hagati yikimenyetso cyahinduwe.
Iki nicyoShenzhen HDV phoelelectron Technology Co., Ltd.. yakuzaniye ibijyanye n'ubumenyi bwo kugabana inshuro nyinshi. Nizere ko iyi ngingo ishobora kugufasha kongera ubumenyi.
