Kana computation ichisvika pamiganho yemuviri yekumhanya kwewachi, isu tinotendeukira kune akawanda-musimboti zvivakwa. Kana kutaurirana kunosvika pamiganho yemuviri yekumhanya kwekufambisa, isu tinotendeukira kune akawanda-antenna masisitimu. Ndeapi mabhenefiti akaita kuti masayendisiti uye mainjiniya vasarudze antenna akawanda sehwaro hwe5G uye kumwe kutaurirana kusina waya? Nepo kusiyana kwenzvimbo yaive yekutanga kukurudzira kwekuwedzera ma antenna pazviteshi zvepasi, zvakaonekwa pakati pemakore ekuma1990 kuti kuisa akawanda antenna paTx uye/kana Rx kudivi kwakavhura mamwe mikana yaisaonekwa neantenna imwechete masisitimu. Iye zvino ngatitsanangurei nzira nhatu huru munyaya ino.
**Inoyevedza**
Beamforming ndiyo yekutanga tekinoroji pakavakirwa iyo yemuviri layer ye5G cellular network. Kune marudzi maviri akasiyana ebeamforming:
Classical beamforming, inozivikanwawo seMutsetse-we-Sight (LoS) kana kugadzirwa kwemuviri
Generalized beamforming, inozivikanwawo seNon-Line-of-Sight (NLoS) kana chaiyo beamforming.
Pfungwa iri kuseri kwemhando mbiri dzekuvhenekesa ndeye kushandisa akawanda antenna kuwedzera simba rechiratidzo kune mumwe mushandisi, uku ichidzvanya masaini kubva kunokanganisa masosi. Sekufananidza, mafirita edhijitari anoshandura chiratidzo chemukati mune frequency domain mukuita kunonzi spectral kusefa. Nenzira imwecheteyo, kupenya kunoshandura chiratidzo chemukati munzvimbo yepasi. Ichi ndicho chikonzero ichinzi zvakare sefa yekusefa.
Kubwinya kwemuviri kune nhoroondo refu mukusainira maalgorithms eiyo sonar uye radar masisitimu. Iyo inogadzira matanda chaiwo munzvimbo yekutapurirana kana kugashira uye nekudaro yakanyatsoenderana nekona yekusvika (AoA) kana kona yekubva (AoD) yechiratidzo. Zvakafanana nemagadzirirwo eOFDM anogadzira nzizi dzakafanana mune frequency domain, classical kana yemuviri beamforming inogadzira matanda anoenderana mune angular domain.
Kune rimwe divi, mukuumbwa kwayo kwakapfava, kwakajairwa kana kugadzirwa chaiko kunoreva kufambisa (kana kugamuchira) masaini mamwechete kubva kune yega Tx (kana Rx) antenna ine kwakakodzera phasing uye kuwana huremu zvekuti simba rechiratidzo rinokwidziridzwa kune mumwe mushandisi. Kusiyana nekudzora danda mune imwe nzira, kutapurirana kana kugashira kunoitika mativi ese, asi kiyi iri kuwedzera zvine hungwaru makopi echiratidzo padivi rekugamuchira kudzikamisa mafambiro akawanda.
**Spatial Multiplexing**
Mune spatial multiplexing modhi, iyo yekuisa data rwizi inokamurwa kuita nzizi dzakawanda dzakafanana munzvimbo yenzvimbo, nerukova rwega rwega rwobva rwaendeswa pamusoro peTx maketani akasiyana. Chero bedzi nzira dzechiteshi dzichisvika kubva kumakona akasiyana zvakakwana paRx antennas, iine inenge isina kuwirirana, dhijitari chiratidzo chekugadzirisa (DSP) hunyanzvi hunogona kushandura isina waya svikiro kuita yakazvimirira yakafanana chiteshi. Iyi MIMO modhi yave iri chinhu chikuru chekurongeka kwehukuru hwekuwedzera kwedata remazuva ano mawaya masystem, sezvo ruzivo rwakazvimiririra rwunofambiswa panguva imwe chete kubva kune akawanda antenna pamusoro peiyo bandwidth yakafanana. Detection algorithms senge zero yekumanikidza (ZF) inopatsanura modulation zviratidzo kubva pakukanganisa kwemamwe antennas.
Sezvinoratidzwa mumufananidzo, muWiFi MU-MIMO, nzizi dzedhata dzakawanda dzinofambiswa panguva imwe chete kuvashandisi vakawanda kubva kune akawanda anotumira antenna.
**Space-Nguva Coding**
Mune iyi modhi, zvirongwa zvekukodha zvakakosha zvinoshandiswa mukati menguva uye antennas zvichienzaniswa neantenna imwe masisitimu, kusimudzira kugashira kusiyanisa kwechiratidzo pasina kurasikirwa kwe data pane anogamuchira. Nzvimbo-yenguva makodhi anosimudzira kusiyana kwenzvimbo pasina kudiwa kwekufungidzira kwechiteshi kune inotapurirana ine akawanda antenna.
Concept Microwave inyanzvi yekugadzira iyo 5G RF zvikamu zveAntenna masisitimu muChina, kusanganisira iyo RF lowpass sefa, highpass sefa, bandpass sefa, notch sefa/bhendi stop sefa, duplexer,Simba divider uye inotungamira coupler. Ese anogona kugadzirwa zvinoenderana nezvinodiwa zvako.
