MIMO thev naus laus zis yog lub tswv yim tseem ceeb hauv kev sib txuas lus wireless.Nws tuaj yeem txhim kho lub peev xwm thiab kev ntseeg siab ntawm wireless channel thiab txhim kho kev sib txuas lus wireless zoo.MIMO tshuab tau siv dav hauv ntau yamwireless kev sib txuas lus systemsthiab tau dhau los ua ib feem tseem ceeb ntawm kev sib txuas lus wireless niaj hnub no.
●MIMO technology ua haujlwm li cas?
MIMO thev naus laus zis siv ntau qhov kev xa tawm thiab txais cov kav hlau txais xov xa thiab txais cov ntaub ntawv.Cov ntaub ntawv kis tau yuav raug muab faib ua ntau lub teeb liab thiab xa mus los ntawm ntau lub kav hlau txais xov xa mus.Ntau lub kav hlau txais xov tau txais cov teeb liab no thiab rov ua dua rau hauv cov ntaub ntawv qub.Cov cuab yeej no tso cai rau ntau cov ntaub ntawv ntws mus rau ntawm tib lub zaus band, yog li ua kom spectral efficiency thiab muaj peev xwm ntawm lub cev.
●Qhov zoo ntawm MIMO technology
Thaum lub xov tooj cua teeb liab tshwm sim, ntau daim ntawv luam ntawm lub teeb liab raug tsim, txhua tus yog cov kwj deg.MIMO thev naus laus zis tso cai rau ntau lub kav hlau txais xov xa mus thiab tau txais ntau qhov spatial kwj tib lub sijhawm, thiab tuaj yeem paub qhov txawv ntawm cov cim xa mus lossis los ntawm cov lus qhia sib txawv.Daim ntawv thov ntawm MIMO thev naus laus zis ua rau qhov chaw muaj peev txheej uas tuaj yeem siv los txhim kho kev ua haujlwm thiab nce kev pabcuam ntawm cov tshuab wireless.
1.Tshaj qhov muaj peev xwm channel
Siv MIMO systems yog ib txoj hauv kev zoo los txhim kho spectral efficiency.Ntau cov kwj deg tuaj yeem xa thiab tau txais ib txhij ntawm MIMO nkag mus thiab tus neeg siv MIMO.Lub peev xwm channel tuaj yeem nce linearly raws li tus naj npawb ntawm cov kav hlau txais xov nce.Yog li, MIMO channel tuaj yeem siv los ua kom muaj peev xwm ua kom lub wireless channel muaj peev xwm.Yog tsis muaj kev nce bandwidth thiab kav hlau txais xov xa xov hluav taws xob, kev siv spectrum tuaj yeem nce ntxiv.
2. Txhim kho channel kev ntseeg tau
Siv cov spatial multiplexing nce thiab spatial ntau haiv neeg tau muab los ntawm MIMO channel, ntau lub kav hlau txais xov tuaj yeem siv los txhawm rau txo qis cov channel.Daim ntawv thov ntawm ntau lub kav hlau txais xov tso cai rau cov ntaub ntawv sib txuas kom xa mus ib txhij, uas tuaj yeem kov yeej cov channel fading thiab txo qhov yuam kev me ntsis.
3. Txhim kho kev tiv thaiv kev cuam tshuam
MIMO thev naus laus zis tuaj yeem txo kev cuam tshuam ntawm cov neeg siv thiab txhim kho kev tiv thaiv kev cuam tshuam ntawm lub network los ntawm ntau lub kav hlau txais xov thiab spatial sib cais tshuab.
4. Txhim Kho Kev Pabcuam
MIMO thev naus laus zis tuaj yeem txhim kho qhov kev pab cuam ntawm lub kaw lus vim MIMO thev naus laus zis tuaj yeem siv ntau lub kav hlau txais xov rau cov ntaub ntawv xa mus, yog li txhim kho lub teeb liab kis tau tus mob thiab muaj peev xwm nkag mus.Thaum kis tau tus mob, yog tias qee lub kav hlau txais xov raug cuam tshuam los ntawm kev thaiv lossis attenuation, lwm cov kav hlau txais xov tseem tuaj yeem txuas ntxiv xa cov ntaub ntawv, yog li txhim kho cov teeb liab.
5.Ua kom haum rau ntau qhov chaw ib puag ncig
MIMO thev naus laus zis tuaj yeem hloov mus rau ntau qhov chaw ib puag ncig.Qhov no yog vim MIMO thev naus laus zis tuaj yeem siv ntau lub kav hlau txais xov rau cov ntaub ntawv xa mus, yog li hloov pauv mus rau ntau qhov chaw ib puag ncig.Thaum lub sijhawm sib kis, cov chaw sib txawv ntawm cov channel yuav muaj kev cuam tshuam sib txawv ntawm cov teeb liab kis tau tus mob, xws li multipath effect, Doppler effect, thiab lwm yam. MIMO thev naus laus zis tuaj yeem hloov kho rau ntau qhov chaw ib puag ncig los ntawm kev siv ntau lub kav hlau txais xov.
Xaus
MIMO thev naus laus zis tau siv dav hauv ntau yam kev sib txuas lus wireless, suav nrog WLAN, LTE, 5G, thiab lwm yam.kev sib txuas lus khoomtus tsim tawm thiab tsim khoom, IWAVE R & D pab pawg tsom mus tsim cov ntaub ntawv mini ruaj ntseg wireless txuas rau lub teeb, me me thiab micro cua tsis siv neeg lub platform thiabhauv av unmanned platforms.
IWAVE tus kheej tsim MESH wireless network khoom siv MIMO thev naus laus zis muaj qhov zoo ntawm kev sib kis ntev, tsis tshua muaj latency, ruaj khov thiab kev txhawb nqa rau ib puag ncig nyuaj.Nws yog dav siv nyob rau hauv cov xwm txheej uas muaj ntau tus neeg, ob peb lub network hauv paus chaw nres tsheb, thiab lub network tsis ruaj khov.Nws yog qhov tsim tshwj xeeb rau kev cawm hauv thaj chaw muaj kev puas tsuaj xws li kev cuam tshuam ntawm txoj kev tam sim ntawd, kev cuam tshuam hauv Is Taws Nem, thiab hluav taws xob poob.
