Iyo kubara byegereye imipaka ifatika yumuvuduko wamasaha, duhindukirira ibintu byinshi-byubatswe.Iyo itumanaho ryegereye imipaka yumubiri wihuta, duhindukirira sisitemu nyinshi.Ni izihe nyungu zatumye abahanga naba injeniyeri bahitamo antene nyinshi nkishingiro rya 5G hamwe n’itumanaho ridafite insinga?Mugihe ubudasa butandukanye aribwo bwambere bwashishikarije kongeramo antene kuri sitasiyo fatizo, byavumbuwe hagati ya za 90 ko gushyira antene nyinshi kuruhande rwa Tx na / cyangwa Rx byafunguye ubundi buryo butari buteganijwe hamwe na sisitemu imwe ya antenne.Reka noneho dusobanure tekinike eshatu zingenzi muriki gice.
** Kumurika **
Beamforming nubuhanga bwibanze bushingiye kumurongo wumubiri wa 5G selile.Hariho ubwoko bubiri butandukanye bwo kumurika:
Kumurika kwa kera, bizwi kandi nka Line-of-Sight (LoS) cyangwa kumurika kumubiri
Kumurika rusange, bizwi kandi nka Non-Line-of-Sight (NLoS) cyangwa ibishusho bifatika
Igitekerezo cyubwoko bubiri bwo kumurika ni ugukoresha antene nyinshi kugirango uzamure imbaraga zerekana ibimenyetso kumukoresha runaka, mugihe uhagarika ibimenyetso biturutse kubangamira isoko.Nukugereranya, sisitemu ya sisitemu ihindura ibimenyetso mubyerekezo byinshyi mubikorwa byitwa gushungura.Muburyo busa, kumurika bihindura ibimenyetso mubisobanuro byumwanya.Iyi niyo mpamvu nayo ivugwa nko kuyungurura umwanya.
Kumurika kumubiri bifite amateka maremare mugutunganya ibimenyetso bya algorithm ya sonar na radar.Itanga imirishyo ifatika mumwanya wo kohereza cyangwa kwakirwa bityo ikaba ifitanye isano rya bugufi nu mpande zo kuhagera (AoA) cyangwa inguni yo kugenda (AoD) yikimenyetso.Bisa nuburyo OFDM ikora imigezi ibangikanye murwego rwumurongo wa interineti, ibisanzwe cyangwa ibimera bifatika bikora imirongo ibangikanye murwego rwimfuruka.
Ku rundi ruhande, mu kwishushanya kwayo kworoheje, kumurika rusange cyangwa kugaragara bisobanura kohereza (cyangwa kwakira) ibimenyetso bimwe kuri buri antenne ya Tx (cyangwa Rx) hamwe nicyiciro gikwiye kandi ukagira uburemere kuburyo imbaraga zerekana ibimenyetso zikoreshwa cyane kubakoresha runaka.Bitandukanye no kuyobora urumuri kumurongo runaka, kwanduza cyangwa kwakirwa bibaho mubyerekezo byose, ariko urufunguzo rwubaka kopi nyinshi yikimenyetso kuruhande rwakiriwe kugirango hagabanuke ingaruka zigenda zishira.
** Kugwiza ahantu **
Muburyo butandukanye bwo guhuza ibintu, ibyinjijwe byamakuru bigabanijwemo imigezi myinshi ibangikanye murwego rwumwanya, hamwe na buri mugezi hanyuma woherezwa kumurongo wa Tx utandukanye.Mugihe cyose inzira zumuyoboro ziva muburyo butandukanye kuri antenne ya Rx, ntaho bihuriye, tekinoroji yo gutunganya ibimenyetso bya digitale (DSP) irashobora guhindura imiyoboro idafite umugozi muburyo bwigenga.Ubu buryo bwa MIMO nicyo kintu cyingenzi cyateganijwe kugirango ubunini bwiyongere bwikigereranyo cyamakuru ya sisitemu igezweho, kubera ko amakuru yigenga atangwa icyarimwe avuye muri antene nyinshi hejuru yumurongo umwe.Gutahura algorithms nka zeru guhatira (ZF) gutandukanya ibimenyetso bya modulasi no kwivanga kwa antene.
Nkuko bigaragara ku gishushanyo, muri WiFi MU-MIMO, amakuru menshi yoherejwe icyarimwe icyarimwe yerekeza kubakoresha benshi kuva antene nyinshi zohereza.
** Umwanya-Igihe Coding **
Muri ubu buryo, gahunda yihariye ya coding ikoreshwa mugihe cyose na antene ugereranije na sisitemu imwe ya antenne, kugirango hongerwe kwakira ibimenyetso bitandukanye nta gihombo cyatanzwe kubakira.Umwanya-umwanya kode yongerera ubudasa butandukanye udakeneye kugereranya umuyoboro kuri transmitter hamwe na antene nyinshi.
Concept Microwave ni uruganda rukora ibikoresho bya 5G RF kuri sisitemu ya Antenna mu Bushinwa, harimo akayunguruzo ka RF yo hasi, akayunguruzo ka hejuru, akayunguruzo, akayunguruzo, akayunguruzo / bande ihagarika akayunguruzo, duplexer, Power divider hamwe na coupler yerekeza.Byose birashobora gutegurwa ukurikije requrements yawe.
