Code Division Multiple Access (CDMA)

Code division multiple access technique is an example of multiple access where several transmitters use a single channel to send information simultaneously. Its features are as follows.

  • In CDMA every user uses the full available spectrum instead of getting allotted by separate frequency.
  • CDMA is much recommended for voice and data communications.
  • While multiple codes occupy the same channel in CDMA, the users having same code can communicate with each other.
  • CDMA offers more air-space capacity than TDMA.
  • The hands-off between base stations is very well handled by CDMA.
