Kusukela ngo-802.11n, ubuchwepheshe be-MIMO buye basetshenziswa kule mithetho yomthetho futhi buye bathuthukisa kakhulu izinga lokudlulisela okungenantambo. Ngokuqondile, indlela yokufeza ukuthuthukiswa kobuchwepheshe obuphezulu. Manje ake sibhekisise ubuchwepheshe be-MIMO. Ngokuqhubeka kobuchwepheshe bokuxhumana obungenawaya, mor...

Kunezinhlobo eziningi zokushintshwa emakethe, kodwa futhi kukhona umehluko ohlukile wokusebenza, futhi izici eziyinhloko zihlukile. Ingahlukaniswa ngokomqondo obanzi nesikali sohlelo lokusebenza: 1) Okokuqala, ngomqondo obanzi, ukushintshwa kwenethiwekhi kungahlukaniswa ngezigaba ezimbili...

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...
