FDMA kont TDMA kont CDMA
Paj sa a sou FDMA kont TDMA kont CDMA bay diferans ant FDMA, TDMA ak teknoloji CDMA. Paj sa a dekri plizyè teknik aksè miltip fè pou sèvi ak resous komen pa itilizatè miltip / abonnés.
FDMA- Frè Divizyon Aksè miltip, isit la se tout bann nan frekans divize an plizyè chanèl RF / transpòtè. Chak konpayi asirans resevwa lajan pou divinò diferan.
Pou egzanp nan tout bann frekans GSM nan 25 megaèrts divize an 124 transpòtè RF nan Pleasant 200 kHz chak. Nan aplikasyon pou Satelit tout bann transponder nan 500 megaèrts se divize an 24 chanèl chak nan 40 MHz Pleasant (36 megaèrts itil ak gwoup gad palè 4MHz).
Gen de kalite prensipal nan FDMA konplo yo itilize nan rezo satelit. SCPC (Single kanal pou chak konpayi asirans) ak MCPC (plizyè kanal pou chak konpayi asirans). MCPC sèvi ak FDM oswa TDM kòm multiplexing konplo.
Gade tou: >>Ki sa ki se diferans ki genyen ant AM ak FM?
• FAMA- Fiks Plasman miltip Aksè, isit la frekans yo pre-atribye ba itilizatè / abonnés / VSATs.
• DAMA- Demand Plasman Aksè miltip, isit la frekans yo dynamique resevwa lajan ki baze sou demann.
#TDMA
TDMA-Tan Divizyon miltip Aksè, isit la se tout Pleasant pataje nan mitan abonnés diferan nan fiks predetermine oswa dinamik asiyen entèval tan / fant. Pou egzanp nan GSM se chak konpayi asirans RF itilize / pataje pa 8 itilizatè nan instants tan diferan.
TDMA itilize TDM multiplexage teknik.
Gade tou: >>AM reseptè vs reseptè FM | Diferans ant reseptè AM ak reseptè FM
CDMA-Kòd Divizyon Aksè miltip, isit la se tout Pleasant pataje nan mitan divinò diferan pa plase kòd inik. Pou egzanp nan CDMA IS-95 la estanda tout antye de 1.225 megaèrts se pataje pa plizyè chanèl / itilizatè lè l sèvi avèk inik 64 Kòd Walsh. Nan CDMA Pleasant tout se ke yo te itilize pa itilizatè tout tan tout tan an ak chak gen kòd inik yo refè done yo. Sistèm nan travay ki baze sou konsèp gaye espèk.
