Isesengura ryimbitse ry'amahame ngiro n'ikoreshwa rya duplexers, triplexers na quadplexers

Muri sisitemu zigezweho z'itumanaho ridafite umugozi, duplexers, triplexers na quadplexers ni ibice by'ingenzi bitagira umugozi kugira ngo hagerwe ku ihererekanya ry'amajwi ry'imirongo myinshi. Bihuza cyangwa bigatandukanya amajwi n'imirongo myinshi y'amajwi, bigatuma ibikoresho byohereza no kwakira imirongo myinshi y'amajwi icyarimwe mu gihe bisangira antene. Nubwo hari itandukaniro mu mazina n'imiterere, amahame yabyo y'ibanze arasa, aho itandukaniro rikomeye ari umubare n'uburemere bw'imirongo y'amajwi ikorwa.

Duplexer

Duplexer igizwe n'amafiriti abiri asangiye umuyoboro umwe (ubusanzwe ni antene) kandi akoreshwa mu gushyira mu bikorwa imirimo yo kohereza (Tx) no kwakira (Rx) ku gikoresho kimwe. Ikoreshwa cyane cyane muri sisitemu ya duplex igabanya inshuro (FDD) kugira ngo hirindwe ko habaho kubangamirana hagati y'amajwi binyuze mu gutandukanya amajwi yo kohereza n'ayo kwakira. Duplexer zisaba urwego rwo hejuru rwo kwitandukanya, ubusanzwe ruri hejuru ya 55 dB, kugira ngo ikimenyetso cyoherejwe kitagira ingaruka ku buryo umuntu yumva.

Triplexer

Triplexer igizwe n'amafiriti atatu asangiye umuyoboro umwe. Yemerera igikoresho gutunganya ibimenyetso bivuye ku mirongo itatu itandukanye y'amajwi icyarimwe kandi ikunze gukoreshwa muri sisitemu z'itumanaho zigomba gushyigikira imirongo myinshi y'amajwi icyarimwe. Imiterere ya triplexer igomba kwemeza ko umurongo wa buri firiti udashyiramo andi mafiriti kandi igatanga ahantu hahagije ho kwitandukanya kugira ngo hirindwe ko habaho kubangamirana hagati y'imirongo y'amajwi.

Quadplexer

Imashini ya quadplexer igizwe n'ama filter ane asangiye umuyoboro umwe. Yemerera igikoresho gutunganya ibimenyetso bivuye ku mirongo ine itandukanye y'ama frequency icyarimwe kandi ikwiriye sisitemu zikomeye z'itumanaho zisaba imikorere myiza ya spectral, nk'ikoranabuhanga ryo guhuza ibyuma. Imiterere ya quadplexer ni myinshi kandi igomba kuzuza ibisabwa bikomeye byo gushyira mu byiciro kugira ngo ibimenyetso biri hagati y'imirongo y'ama frequency bitabangamirana.

Itandukaniro ry'ingenzi

Umubare w'imirongo y'impinduka: Imashini zikora imirongo ibiri y'impinduka, imashini zikora imirongo itatu y'impinduka, naho imashini zikora imirongo ine y'impinduka.

Ubugoranye bw'igishushanyo: Uko umubare w'imirongo y'amajwi wiyongera, ubugoranye bw'igishushanyo n'ibisabwa mu kwitandukanya nabyo biriyongera uko bikwiye.

Uburyo bwo gukoresha: Duplexers zikunze gukoreshwa muri sisitemu z'ibanze za FDD, mu gihe triplexers na quadplexers zikoreshwa muri sisitemu zigezweho z'itumanaho zikenera gushyigikira imirongo myinshi y'amajwi icyarimwe.

Gusobanukirwa uburyo bwo gukora n'itandukaniro rya duplexers, triplexers, na quadplexers ni ingenzi mu gushushanya no kunoza sisitemu z'itumanaho zidafite insinga. Guhitamo ubwoko bwa multiplexer bukwiye bishobora kunoza neza imikoreshereze ya sisitemu n'ubwiza bw'itumanaho.
