Izindaba ezinhle | Ngithole ilungelo lobunikazi le-chip yokuxhumana engenantambo
Ngokuthuthuka okusheshayo kwe-wireless ukuxhumana Ubuchwepheshe, ukubaluleka kwama-chip okuxhumana angenantambo njengengxenye eyinhloko yezinhlelo zokuxhumana ezingenantambo kuya ngokuya kugqama. Ama-chip okuxhumana angenantambo avamile avame ukuba nemisebenzi ezinzile kanye nokuguquguquka okuncane, okwenza kube nzima ukuhlangabezana nezidingo zokuxhumana ezingenantambo ezahlukahlukene. Ukuthuthukiswa kwama-chip okuxhumana angenantambo kuhloselwe ukuhlangabezana nezidingo zokuxhumana ezingenantambo ezimweni ezahlukene, ukuxazulula izinkinga ezikhona kuma-chip okuxhumana angenantambo avamile, ukuthuthukisa ukusebenza kahle kokuxhumana, ukunciphisa amazinga amaphutha, ukuqinisekisa ukuthembeka kokuxhumana kanye nokuzinza, kanye nokukhuthaza intuthuko yomkhakha wama-chip okuxhumana angenantambo.
Injabulo Egcwele EcebileIsixazululo Sobuchwepheshe
1. Ukusebenzisa ubuchwepheshe be-SDR ukufeza izinqubo zokuxhumana ezahlukene kanye nama-frequency band, ukuthuthukisa ukuguquguquka kanye nokukhula kwe-chip.
2.Ukusebenzisa amasu okwakha amandla aphansi kanye nokwenza ngcono ekwakhiweni kwama-chip ukuze kuncishiswe ukusetshenziswa kwamandla futhi kwandiswe isikhathi sokuphila kwamadivayisi.
3. Hlanganisa izingxenye ezibalulekile ezifana nama-transceivers e-RF nama-modem ku-chip efanayo, wehlise inani lezingxenye ezingaphandle, futhi uthuthukise ukuhlanganiswa nokuthembeka.
4. Ukusebenzisa uhlelo lokuxhumana ukuguqula i-analog izimpawuzibe yizibonakaliso zedijithali, izimpawu ze-analog zesikhathi esiqhubekayo ziguqulwa zibe yizibonakaliso zedijithali zesikhathi ezihlukile ngezinqubo zokuthatha amasampula kanye nokulinganisa. Isignali icutshungulwa ngezihlungi zedijithali ezifana nokuhlunga okulwa nokuhlukanisa, ukuhlunga ama-notch, kanye nokulawula ukuthola ukuthuthukisa ikhwalithi yesignali kanye nekhono lokulwa nokuphazamiseka.
5. Ubuchwepheshe bephrothokholi yokuxhumana: Ukuxhumana kanye nokudluliswa kwedatha phakathi kwamadivayisi okuxhumana kufezwa ngezilungiselelo ze-protocol stack ezifana nobukhulu obuphathekayo, ubukhulu besixhumanisi sedatha, ubukhulu benethiwekhi, ubukhulu bezokuthutha kanye nobukhulu besicelo.
Injabulo Egcwele EcebileAmaphuzu Okusungula Izinto Ezintsha
1.Fukulula nokukhula.Ngokusebenzisa izincazelo zesofthiwe yezinqubo zokuxhumana kanye nama-frequency band ngokusebenzisa ubuchwepheshe be-SDR, i-chip ingasekela amazinga amaningi okuxhumana okungenantambo futhi ihlangabezane nezidingo zokuxhumana ezimweni ezahlukene. Okwamanje, ubuchwepheshe be-SDR buvumela nokusebenza kwama-chip ukuthi kuthuthukiswe ngezibuyekezo zesofthiwe ngaphandle kwesidingo sokushintsha amadivayisi ehadiwe.
2. Iyakwazi ukusebenza kahle kakhulu futhi isebenzise amandla aphansi.Le phrojekthi isebenzisa ubuchwepheshe bokuklama obusebenzisa amandla aphansi kanye nama-algorithms okwenza ngcono ukunciphisa ukusetshenziswa kwamandla nokuthuthukisa ukusebenza kahle kokuxhumana. Ngokwenza ngcono ubuchwepheshe obubalulekile njengokuguqulwa kwesimo kanye nokususwa kwamandla, ukucindezelwa kwedatha, kanye nokutholwa kwamandla ngokusebenzisa ubuchwepheshe be-LoRa, ukuxhumana ngamandla aphansi kanye nebanga elide kungafinyelelwa.
3.Ukuhlanganiswa okuphezulu nokuthembeka okuhle.Le phrojekthi ihlanganisa izingxenye ezibalulekile ezifana nama-transceivers e-RF nama-modem ku-chip efanayo, inciphisa inani lezingxenye ezingaphandle futhi ithuthukise ukuhlanganiswa nokuthembeka.
