Kwinkalo yezothutho ezikrelekrele, iinkqubo ze-COFDM zothumelo ezingenazingcingo zingasetyenziswa ekubekeni iliso kwi-traffic, ukulandelela isithuthi, ukulawula umqondiso we-traffic, njl.
Umzekelo, i-100 bits yedatha kufuneka imodareyithwengenxahambisange.Okokuqala yitshintshe ibe ngamasuntswana angama-200,.Xa umqondiso ufunyenwe, nokuba kukho ingxaki yokuhanjiswa kweebhithi ze-100, idatha echanekileyo isenokuthi idilizwe.Ngamafutshane, kukongeza i-redundancy phambi kokumodareyitha ukuphucula ukuthembeka kosulelo.Oku kubizwa ngokuba luLungiso lwempazamo yangaphakathi (FEC) kwiinkqubo ze-COFDM.Kwaye namt yiparameter ebalulekileyo yenkqubo yeCOFDM.
2.2.Ukhathalelo lwezonyango oluhlakaniphile
Kwinkalo yokhathalelo lwezonyango oluhlakaniphileyo, inkqubo yokuhanjiswa kwe-wireless ye-COFDM inokuqonda imisebenzi efana ne-telemedicine, ukusasazwa kotyando olungenazingcingo, kunye nokuhanjiswa kwexesha lokwenyani kwemifanekiso yezonyango, ukuphucula ukusebenza kakuhle kunye nomgangatho weenkonzo zonyango.
2.3.Isixeko esihlakaniphile
Kwinkalo yesixeko esikrelekrele, inkqubo yothumelo engenazingcingo ye-COFDM ingasetyenziswa kukhuseleko lwasezidolophini, ukujonga imekobume, ukukhanya okukrelekrele, njl.njl. ukwandisa inqanaba lobukrelekrele lolawulo lwedolophu kunye nokuphucula umgangatho wobomi babemi.
3.Izinto eziluncedo ze COFDM wireless transmission inkqubo
Xa kuthelekiswa neobunye ubuchwephesha bonxibelelwano obungenazingcingo, inkqubo yothumelo engenazingcingo ye-COFDM inezi nzuzo zilandelayo:
