What is FDMA

Frequency Division Multiple Access (FDMA) is a channel access method used in some multiple access protocols.

FDMA allows multiple users to send data over a single communication channel, such as a coaxial cable or microwave beam, by dividing the channel bandwidth into separate frequency subchannels that do not overlap and assigning each subchannel to a separate user . Users can send data through a subchannel by modulating it on a carrier wave at the frequency of the subchannel. It is used in satellite communication systems and telephone trunk lines.

Difference between FDMA, CDMA and TDMA

Frequency Division Multiple Access (FDMA) :

  • FDMA stands for Frequency Division Multiple Access.
  • In this, bandwidth exchange takes place between different stations.
  • There is no need of any codeword.
  • In this, only one guard band is needed between adjacent channels.
  • Synchronization is not required.
  • The rate of data is low.
  • The data transfer mode is a continuous signal.
  • It is tittle flexible.

Time Division Multiple Access (TDMA) :

  • TDMA stands for Time Division Multiple Access.
  • In this, only the time exchange of the satellite transponder takes place.
  • There is no need of any codeword.
  • In this, the guard time of the adjacent grooves is necessary.
  • The data transfer mode is burst signal.
  • Synchronization is required.
  • The rate of data is medium.
  • It is moderate flexible.

Code Division Multiple Access (CDMA):

  • CDMA stands for Code Division Multiple Access.
  • In this, both i.s. the bandwidth and time between the different stations is produced.
  • codeward is necessary.
  • In this, both the guard band and guard time are necessary.
  • synchronization is not required.
  • The data transfer mode is digital signal.
  • It is highly flexible
