Ikoranabuhanga rya MIMO rikoresha antene nyinshi mu kohereza no kwakira ibimenyetso murwego rwitumanaho ridafite umugozi.Antenne nyinshi kubohereza no kubakira byongera cyane imikorere yitumanaho.Ikoranabuhanga rya MIMO rikoreshwa cyane cyane muriitumanaho rigendanwaimirima, iri koranabuhanga rirashobora kuzamura cyane ubushobozi bwa sisitemu, igipimo cyo gukwirakwiza, hamwe n’ikigereranyo cyerekana urusaku (SNR).
1.Ubusobanuro bwa MIMO
Ikoranabuhanga rya MIMO Wireless Itumanaho ryitwa Multiple-Input Multiple-Out-put (Multiple-Input Multiple-Out-put) tekinoroji, kandi irashobora kandi kwitwa Multiple Transmit Multiple Receive Antenna (MTMRA, Multiple Transmit Multiple Receive Antenna).
Ihame ryibanze ryayo ni ugukoresha antene nyinshi zohereza no kwakira antene ku ihererekanyabubasha no kwakira iherezo, kandi ukabasha gutandukanya ibimenyetso byoherejwe cyangwa biva mu cyerekezo gitandukanye.Irashobora kandi kuzamura ubushobozi bwa sisitemu, gukwirakwiza no kugereranya ibimenyetso-by-urusaku bitiyongereyeho umurongo wa interineti no kohereza ingufu, no kunoza ihererekanyabubasha ry’ibimenyetso bidafite umugozi.
Iratandukanye nuburyo gakondo bwo gutunganya ibimenyetso muburyo bwiga ibibazo byo gutunganya ibimenyetso uhereye igihe n'umwanya.Nkuko bigaragara ku gishushanyo gikurikira, iyo ni sisitemu ya MIMO hamwe na antenne ya Nt na Nr kuri transmitter hamwe niyakira.
Sisitemu yoroshye ya MIMO
2.Icyiciro cya MIMO
Ukurikije imiterere itandukanye hamwe nibidukikije bidafite umugozi, ibikurikira nuburyo bune bukoreshwa muburyo bwa MIMO: SISO, MISO na SIMO.
3.Ibyingenzi byingenzi muri MIMO
Hariho ibitekerezo byinshi bigira uruhare muri MIMO, ibyingenzi muri byo ni bitatu bikurikira: gutandukana, kugwiza no kumurika.
Gutandukana no kugwiza bivuga uburyo bubiri bwakazi bwa tekinoroji ya MIMO.Hano tuzakwereka ibitekerezo byibanze.
Ibinyuranye: bivuga kohereza ibimenyetso bimwe munzira nyinshi zigenga.Nukuvuga, ikimenyetso kimwe, imiyoboro yigenga.
Ip Multiplexing: bivuga kohereza ibimenyetso byinshi byigenga munzira imwe.Nukuvuga, ibimenyetso bitandukanye, imiyoboro isanzwe.
Hano dukoresha imbonerahamwe kugirango twerekane muri make isano hagati yabo.
| Uburyo bwo gukora | Intego | Inzira | Ibisobanuro |
| Ibinyuranye | Kunoza kwizerwa | Mugabanye gushira | Umwanya-Igihe Kode |
| Kugwiza | Kunoza ibicuruzwa | Wungukire gushira | Kugwiza ahantu |
Hanyuma, reka tuvuge kubyerekeye kumurika.Hano tuzaguha kandi igitekerezo cyibanze: ni tekinoroji yo gutunganya ibimenyetso ikoresha sensor array yohereza no kwakira ibimenyetso mubyerekezo.Nugukora ibimenyetso byoherejwe na antenne kurushaho kuyobora, nibyiza ko ushobora kwerekanwa neza kubakoresha nta mbaraga zisohoka.
● Mugihe cya 1, sisitemu ya antenne irasa hafi yingufu zingana mubyerekezo byose.Hatitawe ku ntera iri hagati y’abakoresha batatu na sitasiyo fatizo, nubwo buri mukoresha ashobora kubona imbaraga zingana zingana, haracyari umubare munini wibimenyetso byakwirakwijwe mumwanya wubusa, bitera gutakaza ingufu muri sitasiyo fatizo.
● Mugihe cya 2, imirasire yingufu ya antenne irayobora cyane, ni ukuvuga, ingufu nini zishoboka mucyerekezo aho uyikoresha abaho kandi ingufu zigabanywa hafi mubyerekezo bidafite akamaro.Tekinoroji ikora ibimenyetso bya antenne nicyo twita beamforming.
4.Ibyiza bya MIMO
Gutezimbere ubushobozi bwumuyoboro
Sisitemu ya MIMO irashobora kongera ubushobozi bwumuyoboro mugihe kinini cyerekana ibimenyetso-by-urusaku kandi birashobora gukoreshwa mubihe aho imiyoboro idashobora kubona amakuru yumuyoboro.Irashobora kandi kongera igipimo cyo kohereza amakuru itarinze kwaguka kwaguka na antenne imbaraga zo gukwirakwiza, bityo bikazamura cyane imikoreshereze yikigereranyo.
Umuyoboro wizewe
Gukoresha tekinoroji ya tekinoroji itandukanye itangwa numuyoboro wa MIMO birashobora kuzamura cyane ituze rya sisitemu no kongera umuvuduko.
Umwanzuro
FDM-6680ni SWaP nkeya, igiciro gito cya 2x2 radio MIMO itanga amakuru maremare mugace gakoreramo hamwe nigipimo cyamakuru 100-120Mbps.Ibisobanuro birambuye nyamuneka suraIWAVEurubuga.
