Kana kuenzanisirwa kwaswedera kumiganhu yemuviri wekumhanya kwemakungwa, isu tinotendeukira kune akawanda-core architectures. Kana kutaurirana kuswedera miganhu yemuviri yekukurumidza kutumira, tinotendeukira kune akawanda-antenna masisitimu. Ndezvipi zvakanakira masayendisiti uye mainjiniya kuti vasarudze allple atennas sehwaro hwe5g uye humwe husina waya kutaurirana? Nepo kusiyana kwespatiity ndiko kwekutanga kukurudzira kwekuwedzera antennas Ngatirondedzere izvozvi maitiro matatu makuru mune izvi mamiriro.
** Beamforming **
Beammining ndiyo yekutanga tekinoroji iyo iyo denderedzwa remuviri we 5g cellular network yakavakirwa. Kune marudzi maviri akasiyana ezvekusiyana:
Classical Beamforming, inozivikanwawo seye-ye-yekuona (los) kana yemuviri Beamforming
Generalsised Beamforming, zvakare inozivikanwa seisiri-mutsara-we-kuona (Nlos) kana Virtual Beammforming
Pfungwa iri kumashure kwemarudzi ese emhando yekushandisa huwandu hwekushandisa akawanda antennas kusimudzira simba kune mumwe mushandisi, uchidzvinyirira masaini kubva pakurindira zvinyorwa. Semunhu fananidzo, fananidzo yedhijitari inoshandura zviratidzo zvemukati mune frequency domain mune maitiro anonzi spectral yekuputika. Nenzira yakafanana, Beammforming Actters chiratidzo zvirimo mune spatial domain. Ndokusaka zvichinzi zvakare zvichitaurwa spatial kusefa.
Beofming yemuviri ine nhoroondo refu mune chiratidzo chekugadzirisa algorithms yeSonar uye Radar Systems. Inoburitsa matanda chaiwo munzvimbo yekutapurirwa kana kugamuchira uye nokudaro zvakanyatsoenderana nekona yekusvika (AOA) yekubva (AOD) yeChiratidzo. Zvakafanana nekuti yeDDDM inogadzira huwandu hwefanana neye frellency domain, classical kana yemuviri Beamforming inogadzira matanda akafanana mune angular domain.
Kune rimwe divi, mune iri nyore kusimba, yakajairika Kusiyana nedombo renyama mune imwe nzira, kutapurirana kana kugamuchira kunhivi dzose, asi kiyi iri kuwedzera makopi akawanda echiratidzo chekugadzirisa kuderedza mari yekufambisa.
** Spatial akawandaxing **
Mune spatial akawandaxing mode, iyo yekuisa data rwizi rwakakamurwa muhuremu hwakafanana mune spatial domain, nedanho rimwe nerimwe rakazotumirwa pamusoro pechiketani tx. Chero bedzi nzira nzira dzinosvika kubva kumakona akaparadzaniswa neRX Atennas, pasina kuwirirana, Digital chiratidzo Iyi mimo maitiro akave chinhu chikuru chekurongeka kwehukuru hwekuwedzera kwehurongwa hwemaya emanheru Kuongororwa algorithms kunge zero kumanikidza (ZF) kwakaparadzanisa zviratidzo zvekutumira kubva mukukanganisa kweimwe antennas.
Sezvinoratidzwa muchimiro, muWiFi Mu-mimo, akawanda data data ari panguva imwe chete inotapurirana kune vazhinji vashandisi kubva kuwanda kufambisa antennas.
** nzvimbo-nguva coding **
Mune iyi mode, inokosha yekubatanidza zvirongwa zvinoshandiswa pane nguva uye antennas yakafananidzwa neye Antenna masisitimu, kusimudzira kugashira kusaina madhiri pasina chero data kurasikirwa kwedata kune anogamuchira. Space-nguva macodes inosimudzira spatial kusiana pasina kudiwa kwekutenderera kweturity kuTransmitter ine akawanda antennas.
Plents microwave mugadziri we5G RF zvikamu zveAntenna Systems muChina, Highpass Filter, Notch Filter / Duplexer, Simba Divider uye kutungamira Cliver. Ese anogona kuve akagadziridzwa zvinoenderana nezvinodiwa zvako.
