      Imigaqo yobuGcisa eSisiseko ye-MIMO

      Ukusukela kwi-802.11n, itekhnoloji ye-MIMO isetyenzisiwe kule protocol kwaye iphucule kakhulu izinga lokuhanjiswa kwamacingo. Ngokukodwa, indlela yokuphucula iteknoloji ephezulu. Ngoku makhe sijonge ngakumbi kwitekhnoloji ye-MIMO. Ngenkqubela phambili yetekhnoloji yonxibelelwano engenazingcingo, mor...

      Unxibelelwano oluthe ngqo oluSasazwayo (i-DSSS) – uMmiselo woNxibelelwano

      Umgaqo-siseko: Umgaqo wenkqubo ye-Spectrum ye-Direct Sequence Spread Spectrum ilula kakhulu. Umzekelo, umtya wolwazi oza kuthunyelwa uyandiswa ukuya kwibhendi ebanzi kakhulu ngekhowudi ye-PN. Kwisiphelo sokufumana, ulwazi oluthunyelweyo lufunyanwa ngokunxibelelanisa isiginali yesspectrum kunye ...

      Intshayelelo yoBukhulu beVector yeMposiso (EVM)

      I-EVM: isifinyezo soBukhulu beVektha yeMposiso, nto leyo ithetha ukuba imposiso ye-amplitude yevektha. Ukuhanjiswa kwebhendi yesiginali yedijithali kukumodareyitha isiginali ye-baseband ekupheleni kokuthumela, ukuyithumela kumgca wokuhanjiswa, kwaye emva koko uyithobe ekupheleni kokufumana ukubuyisela isiseko sokuqala...

      Imo yoThutho lweDatha kunye noMgaqo wokuSebenza

      Umgaqo osebenzayo: Emva kokuba nayiphi na i-node yokutshintsha ifumana umyalelo wokuhanjiswa kwedatha, ikhangela ngokukhawuleza itafile yedilesi egcinwe kwimemori ukuqinisekisa indawo yokudibanisa yekhadi lenethiwekhi kunye nedilesi ye-MAC kwaye emva koko idlulisela idatha kwi-node. Ukuba indawo ehambelana nayo ...
