Lapho ukuhlanganiswa kusondela emikhawulweni ebonakalayo yejubane lewashi, siphendukela kwizakhiwo eziningi ezibalulekile. Lapho ukuxhumana kusondela emikhawulweni ebonakalayo yejubane lokudlulisela, siphendukela ezinhlelweni eziningi ze-antenna. Yiziphi izinzuzo ezaholela ososayensi nonjiniyela ukuba bakhethe izinduna eziningi njengesisekelo se-5G nakwezinye ukuxhumana okungenantambo? Ngenkathi ukwehluka kwe-Spatial kwakuyisisusa sokuqala sokwengeza izimpondo eziteshini ezisezindaweni, kwatholakala maphakathi nawo-1990s afaka ama-antenna amaningi e-TX kanye / noma i-RX Side avule amanye amathuba angenakulindeleka ezinhlelweni ezizodwa ze-antenna. Manje ake sichaze amasu amathathu amakhulu kulo mongo.
** Beamforming **
I-Beangforming ubuchwepheshe obuyisisekelo lapho ungqimba lwe-3G amaselula asuselwa khona. Kunezinhlobo ezimbili ezahlukene ze-beangforming:
I-Classical Beamform, eyaziwa nangokuthi-key-of-sight (los) noma i-brictforming
I-Genelized Broungforming, eyaziwa nangokuthi ukungaboni okukodwa
Umqondo ngemuva kwezinhlobo zombili ze-beamforming ukusebenzisa ama-antennas amaningi ukuthuthukisa amandla wesiginali abheke kumsebenzisi othize, ngenkathi kucindezela amasiginali emithonjeni ethintana nayo. Njenge-anology, izihlungi zedijithali ziguqula okuqukethwe kwesiginali kusizinda semvamisa kwinqubo ebizwa ngokuthi ukuhlunga okubukeli. Ngendlela efanayo, okuqukethwe kwe-Beangform.com okuqukethwe kwesiginali esizindeni sendawo. Kungakho kubizwa nangokuthi ukuhlunga kwendawo.
I-Bouth Braiff inomlando omude ekusebenzeni kwama-algorithms ama-algorithms ama-sonar kanye nama-radar. Ikhiqiza imishayo yangempela esikhaleni sokudlulisela noma ukwamukela futhi ihlobene kakhulu ne-angle yokufika (AOA) noma i-angle yokusuka (aod) yesiginali. I-IxDM idala imifudlana ehambisanayo kwisizinda semvamisa, i-classical noma emzimbeni we-beangform idala imishayo ehambisanayo esizindeni se-angular.
Ngakolunye uhlangothi, ekucabangeni kwayo okulula kakhulu, ukuguquguquka okujwayelekile noma okubonakalayo okusho ukudlulisa (noma ukwamukela) amasiginali afanayo avela ku-TX (noma Rx) aqukethe izigaba ezifanele futhi athole isisindo esinjalo amandla esiginali akhuliswa kumsebenzisi othize. Ngokungafani nokuqondisa emzimbeni kogongolo oluthile, ukuhambisa noma ukwamukela kwenzeka kuzo zonke izinkomba, kepha ukhiye wengeza amakhophi amaningi wesiginali ohlangothini lokuthola i-Multipath Deling.
** I-Spatial MulkeXing **
Kwindlela yokufaka i-Spatial MultileXing, ukusakazwa kwedatha yokufaka kuhlukaniswe ngemifudlana efanayo esizindeni sendawo, ngokusakazwa ngakunye bese kudluliselwa ngaphezulu kwamaketanga we-TX ama-TX. Uma nje izindlela zesiteshi zifika ezivela e-angles ezahlukene e-RX antennas, cishe azikho izindlela zokuhlangana, amasu we-Digital Signal (DSP) angaguqula indlela engenantambo eziteshini ezizimele ezizimele. Le modi ye-mimo ibe yinto enkulu yokuhleleka kobukhulu kukhuphuka ngezinga ledatha yezinhlelo zesimanje zama-wireless, ngoba imininingwane ezimele idluliselwa kanyekanye kusuka kuma-antennas amaningi ngaphezulu komkhawulokudonsa ofanayo. Ukutholwa kwama-algorithms afana ne-zero ukuphoqa (zf) Hlukanisa izimpawu zokushintshana kusuka ekuphazanyisweni kwezinye izimpondo.
Njengoba kukhonjisiwe kwisibalo, eWiFi Mu-Mimo, ukusakazwa kwedatha eminingi kudluliselwa ngasikhathi sinye kubasebenzisi abaningi kusuka kuma-antennas amaningi adlulisa.
** I-Space-time coding **
Kule modi, amacebo akhethekile wokufaka amakhodi aqashwa ngasikhathi kanye nezimpondo eziqhathaniswa nezinhlelo ezizodwa ze-antenna, ukuthuthukisa ukuhlukahluka kwesiginali ngaphandle kokulahleka kwesilinganiso sedatha kulowo owamukelayo. Amakhodi wesikhathi sesikhathi athuthukisa ukwahlukahlukana kwendawo ngaphandle kwesidingo sokulinganisa kwesiteshi ku-transmitter enezimpondo eziningi.
I-Concept Microwave ngumkhiqizi ochwepheshe wezakhi ze-5G RF zezinhlelo ze-antenna eChina, kufaka phakathi isihlungi se-RF Lowpass, isihlungi se-bandppass, isihlungi se-bandch, i-coupler ephakemeyo. Zonke zingenziwa ngokwezifiso ngokuya ngokwalokho okuvuselelayo kwakho.
