Chidziwitso

Mfundo: Mfundo ya Direct Sequence Spread Spectrum system ndiyosavuta. Mwachitsanzo, zidziwitso zambiri zomwe ziyenera kutumizidwa zimakulitsidwa kukhala gulu lalikulu kwambiri kudzera pa PN code. Pamapeto olandila, zomwe zatumizidwa zimabwezedwa polumikizana ndi sipekitiramu yofalikira ndi ...

EVM: Chidule cha Error Vector Magnitude, kutanthauza kukula kwa vekitala yolakwika. Kutumiza kwa digito ma frequency band ndikusinthira siginecha ya baseband kumapeto kotumiza, kuitumiza pamzere kuti itumizidwe, kenako ndikuyitsitsa pamapeto olandila kuti abwezeretsenso choyambirira ...

Mfundo yogwira ntchito: Node iliyonse yosinthira ikalandira lamulo lotumizira deta, imasaka mwachangu patebulo la adilesi yosungidwa kukumbukira kuti itsimikizire malo olumikizirana ndi ma netiweki adilesi ndi adilesi ya MAC ndikutumiza deta ku node. Ngati malo ogwirizana ndi ...

Ma modules osiyanasiyana amtundu wachitatu pamsika ali ndi ubwino waukulu pamtengo poyerekeza ndi ma modules oyambirira optical, omwe amatha kuthetsa bwino vuto la mtengo wapamwamba wotumizira ma modules optical. Komabe, anthu ena amadandaulabe za mtundu wa ma module optical ogwirizana. HDV...

Monga momwe tawonetsera pamwambapa, tikhoza kumvetsetsa maonekedwe a RJ45 malinga ndi chithunzicho, koma osati mawonekedwe onse a RJ45 monga omwe ali pamwambawa ndi RJ11 interfaces, zomwe sizidzakambidwa kwakanthawi. Zosinthazi zimakonzedwa mbali ndi mbali ndi madoko angapo a RJ45, omwe ...

Nthawi zambiri, kuyanjana kwa ma module owoneka kumatanthawuza ngati ma module amatha kugwira ntchito bwino pazida zoyankhulirana zamitundu yosiyanasiyana ndi opanga. Tekinoloje zomwe zili m'ma module optical ndizochepa, ndipo mawu awo oyamba ndi osavuta. Chifukwa chake, ambiri ...
