Ulwazi

Isimiso: Isimiso se-Direct Sequence Spread Spectrum system silula kakhulu. Isibonelo, uchungechunge lolwazi oluzothunyelwa lunwetshwa lube yibhendi yefrikhwensi ebanzi kakhulu ngekhodi ye-PN. Ekupheleni kokwamukela, ulwazi oluthunyelwe lubuyiswa ngokuhlobanisa isiginali ye-spectrum yokusabalalisa ne ...

I-EVM: isifinyezo se-Error Vector Magnitude, okusho ubukhulu be-vector yephutha. Ukudluliswa kwebhendi yesignali yedijithali ukulungisa isiginali ye-baseband ekugcineni kokuthumela, ukuyithumela emugqeni ukuze idluliselwe, bese uyehlisa ekugcineni kokwamukela ukuze kubuyiselwe i-baseband yangempela...

Umgomo wokusebenza: Ngemuva kokuthi noma iyiphi i-node ye-switch ithola umyalo wokudlulisa idatha, isesha ngokushesha ithebula lekheli eligcinwe kumemori ukuze iqinisekise indawo yokuxhuma yekhadi lenethiwekhi nekheli le-MAC bese idlulisela idatha endaweni. Uma indawo ehambisanayo ingu...

Amamojula ahlukahlukene e-third party optical emakethe anezinzuzo ezinkulu ezindlekweni uma kuqhathaniswa namamojula okuqala optical, angaxazulula ngokuphumelelayo inkinga yezindleko eziphezulu zokuthunyelwa kwamamojula optical. Noma kunjalo, abanye abantu basakhathazeka ngekhwalithi yamamojula ahambisanayo optical. I-HDV...

Njengoba kuboniswe esithombeni esingenhla, singakuqonda ukubukeka kwe-RJ45 ngokusho kwesithombe, kodwa akuzona zonke izixhumanisi ze-RJ45 ezifana nalezi ezingenhla ziyi-interface ye-RJ11, okungeke kuxoxwe ngayo okwesikhashana. Amaswishi ahlelwe eceleni ngamachweba amaningi e-RJ45, angaba...

Ngokuvamile, ukuhambisana kwamamojula optical kubhekisela ekutheni amamojula angasebenza ngokujwayelekile yini ezintweni zokuxhumana zemikhiqizo ehlukene kanye nabakhiqizi. Okuqukethwe kobuchwepheshe bamamojula optical kuphansi, futhi isingeniso sabo silula. Ngenxa yalokho, abaningi ...
