Ubuchwepheshe be-MIMO wumqondo obalulekile kubuchwepheshe bokuxhumana okungenazintambo.Ingathuthukisa kakhulu umthamo nokuthembeka kwamashaneli angenawaya futhi ithuthukise ikhwalithi yokuxhumana okungenantambo.Ubuchwepheshe be-MIMO busetshenziswe kabanzi ezinhlobonhloboamasistimu okuxhumana angenantambofuthi isibe yingxenye ebalulekile yobuchwepheshe besimanje bokuxhumana okungenazintambo.
●Ngabe ubuchwepheshe be-MIMO busebenza kanjani?
Ubuchwepheshe be-MIMO busebenzisa ama-antenna amaningi okuthumela nokwamukela ukuthumela nokwamukela idatha.Idatha edlulisiwe izohlukaniswa ngamasignali amancane amaningi futhi ithunyelwe ngama-antenna amaningi ngokulandelanayo.Ama-antenna amaningi atholayo athatha lawa masignali amancane futhi awahlanganise kudatha yangempela.Lobu buchwepheshe buvumela ukusakazwa kwedatha okuningi ukuthi kudluliselwe kubhande lefrikhwensi efanayo, ngaleyo ndlela kwandise ukusebenza kahle kokubukeka kanye namandla esistimu.
●Izinzuzo zobuchwepheshe be-MIMO
Uma isignali yomsakazo ibonakala, amakhophi amaningi esignali akhiqizwa, ngalinye eliwukusakazwa kwendawo.Ubuchwepheshe be-MIMO buvumela izimpondo eziningi ukuthi zidlulise futhi zamukele imifudlana eminingi yendawo ngesikhathi esisodwa, futhi bungahlukanisa amasiginali athunyelwa noma asuka eziqondisweni zendawo ezihlukene.Ukusetshenziswa kobuchwepheshe be-MIMO kwenza indawo ibe yinsiza engasetshenziswa ukuthuthukisa ukusebenza nokwandisa ukumbozwa kwamasistimu angenawaya.
1.Khulisa umthamo wesiteshi
Ukusebenzisa izinhlelo ze-MIMO kuyindlela ephumelelayo yokuthuthukisa ukusebenza kahle kwe-spectral.Ukusakazwa kwendawo okuningi kungathunyelwa futhi kwamukelwe ngesikhathi esisodwa phakathi kwendawo yokufinyelela ye-MIMO neklayenti le-MIMO.Umthamo wesiteshi ungakhula ngokomugqa njengoba inani lezinti likhula.Ngakho-ke, isiteshi se-MIMO singasetshenziswa ukukhulisa ngokuphawulekayo umthamo wesiteshi esingenantambo.Ngaphandle kokwenyuka komkhawulokudonsa kanye namandla okudlulisa izinti, ukusetshenziswa kwe-spectrum kungandiswa kakhulu.
2.Thuthukisa ukuthembeka kwesiteshi
Ngokusebenzisa inzuzo yokuphindaphinda kwendawo kanye nenzuzo yokuhlukahluka kwendawo ehlinzekwa yisiteshi se-MIMO, izimpondo eziningi zingasetshenziswa ukucindezela ukufiphala kwesiteshi.Ukusetshenziswa kwezinhlelo zama-antenna amaningi kuvumela ukusakazwa kwedatha okuhambisanayo ukuthi kudluliselwe ngesikhathi esisodwa, okunganqoba kakhulu ukufiphala kwesiteshi futhi kunciphise izinga lephutha elincane.
3.Thuthukisa Ukusebenza Okungaphazanyiswa
Ubuchwepheshe be-MIMO bunganciphisa ukugxambukela phakathi kwabasebenzisi futhi buthuthukise ukusebenza kokuvimbela ukuphazamiseka kwenethiwekhi ngama-antenna amaningi kanye nobuchwepheshe bokuhlukanisa indawo.
4.Thuthukisa Ukusabalala
Ubuchwepheshe be-MIMO bungathuthukisa ukumbozwa kwesistimu ngoba ubuchwepheshe be-MIMO bungasebenzisa izimpondo eziningi ukuze kudluliselwe idatha, ngaleyo ndlela kuthuthukiswe ibanga lokudluliswa kwesignali namandla okungena.Ngesikhathi sokudlulisa, uma ezinye izimpondo zithintwa ukuvinjwa noma ukuncishiswa, amanye ama-antenna asengaqhubeka nokudlulisa idatha, ngaleyo ndlela enze ngcono ukumbozwa kwesignali.
5.Zijwayelane Nezimo Ezihlukahlukene Zesiteshi
Ubuchwepheshe be-MIMO bungakwazi ukuzivumelanisa nezimo ezihlukahlukene zeziteshi.Lokhu kungenxa yokuthi ubuchwepheshe be-MIMO bungasebenzisa izinti eziningi zokudlulisa idatha, ngaleyo ndlela zivumelane nezinguquko ezindaweni ezihlukahlukene zeziteshi.Phakathi nenqubo yokudlulisela, izindawo ezihlukene zamashaneli zingaba nomthelela ohlukile ekudluliselweni kwesignali, njengomphumela we-multipath, umphumela we-Doppler, njll. Ubuchwepheshe be-MIMO bungavumelanisa nezinguquko ezindaweni ezihlukahlukene zamashaneli ngokusebenzisa izinti eziningi.
Isiphetho
Ubuchwepheshe be-MIMO busetshenziswe kabanzi ezinhlelweni zokuxhumana ezingenantambo, okuhlanganisa i-WLAN, LTE, 5G, njll. Njengochwepheshe.umkhiqizo wokuxhumanaumthuthukisi kanye nomkhiqizi, ithimba le-IWAVE R&D ligxile ekwakheni isixhumanisi sedatha engenantambo evikelekile emincane yokukhanya, amapulatifomu amancane nomoya omncane ongenamuntu kanyeamapulatifomu angenamuntu.
Imikhiqizo yenethiwekhi engenantambo ye-IWAVE ethuthukisiwe ye-MESH yamukela ubuchwepheshe be-MIMO inezinzuzo zebanga elide lokudlulisela, ukubambezeleka okuphansi, ukudluliswa okuzinzile nokusekelwa kwezindawo eziyinkimbinkimbi.Isetshenziswa kakhulu ezimeni lapho kunabantu abaningi, iziteshi ezimbalwa zenethiwekhi yomphakathi, kanye nenethiwekhi engazinzile.Kuwumklamo okhethekile wokuhlenga ezindaweni zezinhlekelele ezifana nokuphazamiseka kwemigwaqo kungazelelwe, ukunqanyulwa kwe-inthanethi, nokuphela kukagesi.
