Question

The different access methods which permit many satellite users to operate in parallel through a single transponder without interfering with each other as _____.

• A. Frequency Division Multiple Access (FDMA)
• B. Time Division Multiple Access (TDMA)
• C. Code Division Multiple Access (CDMA)
• D. All of these

Answer 1

The correct option is D All of these

• Frequency Division Multiple Access (FDMA) is one of the most common analogue multiple access methods. The frequency band is divided into channels of equal bandwidth so that each conversation is carried on a different frequency .
• Time Division Multiple Access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots.The users transmit in rapid succession, one after the other, each using its own time slot.
• Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.
