Ukuxhumana ngesathelayithi kudlala indima ebalulekile ezisetshenzisweni zanamuhla zempi kanye nezomphakathi, kodwa ukuthambekela kwayo ekuphazamisekeni kuye kwaholela ekuthuthukisweni kwamasu ahlukahlukene okulwa nokuvinjelwa. Lesi sihloko sifingqa ubuchwepheshe obuyisithupha obubalulekile bangaphandle: i-spread spectrum, ikhodi kanye nokuguqulwa, i-antenna anti-jamming, ukucubungula ngaphakathi, ukucubungula i-transform-domain, kanye nokucubungula i-amplitude-domain, kanye namasu okuxhumanisa aguquguqukayo, ukuhlaziya izimiso nezinhlelo zokusebenza zawo.
1. Ubuchwepheshe be-Spread Spectrum
I-spread spectrum ithuthukisa ikhono lokulwa nokujikijela ngokwandisa i-bandwidth yesignali, ukunciphisa ubuningi be-spectral yamandla. I-Direct Sequence Spread Spectrum (DSSS) isebenzisa amakhodi angahleliwe ukuze yandise i-bandwidth yesignali, ihlakaze amandla okuphazamiseka kwe-narrowband. Lokhu kubalulekile ekuxhumaneni kwesathelayithi yezempi, ilwa nokujikijela ngamabomu (isb., ukuphazamiseka komsindo we-co-frequency noma i-broadband) ukuqinisekisa ukudluliswa okuphephile komyalo kanye nobuhlakani.
2. Ubuchwepheshe Bokubhala Amakhodi Nokushintshashintsha
Amakhodi okulungisa amaphutha athuthukisiwe (isb., Amakhodi e-Turbo, i-LDPC) ahlanganiswe nokuguqulwa kwe-oda eliphezulu (isb., i-PSK, i-QAM) athuthukisa ukusebenza kahle kwe-spectral ngenkathi enciphisa amaphutha abangelwa ukuphazamiseka. Isibonelo, i-LDPC ene-QAM ephezulu ithuthukisa izinsizakalo zesathelayithi zezentengiselwano (isb., i-HDTV, i-inthanethi) futhi iqinisekisa ukuxhumana okuqinile kwezempi ezindaweni eziphikisanayo.
3. Ubuchwepheshe Bokulwa Nokuvinjelwa Kwe-Antena
Ama-antenna aguquguqukayo nahlakaniphile alungisa amaphethini emisebe ngokuguquguqukayo ukuze aqede ama-jammer. Ama-antenna aguquguqukayo aqondisa ama-null emithonjeni yokuphazamiseka, kuyilapho ama-antenna ahlakaniphile esebenzisa ukucubungula kwe-multi-array ukuze kuhlungwe indawo. Lawa abalulekile ku-SATCOM yezempi ukuze kulwiwe nezinsongo zempi ze-elekthronikhi.
4. Ubuchwepheshe Bokucubungula Ebhodini (i-OBP)
I-OBP yenza ukuhlukaniswa kwesignali, ukuqopha ikhodi, kanye nokuhambisa ngqo kumasathelayithi, kunciphisa ubuthakathaka bokudluliselwa komhlaba. Izinhlelo zempi zifaka phakathi ukucubungula okuphephile kwendawo ukuvimbela ukulalelwa kwemiyalezo kanye nokwabiwa kwezinsizakusebenza okulungiselelwe ukuze kusebenze kahle.
5. Ukucubungula i-Transform-Domain
Amasu afana ne-FFT kanye ne-wavelet aguqula amasignali abe yizizinda zemvamisa noma zemvamisa yesikhathi ukuze kuhlungwe ukuphazamiseka. Lokhu kulwa ne-broadband kanye nokuxinana kwesikhathi okuhlukahluka, kuthuthukisa ukuzivumelanisa nezimo ezindaweni eziyinkimbinkimbi ze-electromagnetic.
6. Ukucutshungulwa Kwesizinda Sokuphakama
Imikhawulo kanye ne-Automatic Gain Control (AGC) zivimbela ukuphazamiseka okunamandla okungazelelwe (isb., umbani noma ukuminyana kwesitha), ukuvikela amasekethe okwamukela kanye nokugcina ukuzinza kwezixhumanisi.
7. Ubuchwepheshe Besixhumanisi Esiguquguqukayo
Ukulungiswa kwesikhathi sangempela kokubhala ikhodi, ukushintshashintsha, kanye namazinga edatha ngokusekelwe ezimweni zesiteshi (isb., i-SNR, i-BER) kuqinisekisa ukuxhumana okuthembekile naphezu kwesimo sezulu noma ukuminyana. Izinhlelo zempi zisebenzisa lokhu ukuze zikwazi ukumelana nezimo zempi ezishintshashintshayo.
Isiphetho
Ubuchwepheshe bangaphandle bokulwa nokuvinjelwa kwe-jamming busebenzisa izindlela eziningi ezihlanganisa ukucubungula amasignali, ukufaka amakhodi, kanye nezinhlelo eziguquguqukayo. Ukusetshenziswa kwezempi kubeka phambili ukuqina nokuphepha, kuyilapho izinhlelo zezentengiselwano zigxila ekusebenzeni kahle. Intuthuko yesikhathi esizayo ingahlanganisa i-AI kanye nokucubungula kwesikhathi sangempela ukuze kulwiswane nezinsongo ezishintshayo.
