What is the full form of CDMA ?

CDMA - Code Division Multiple Access

Code Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques and a special coding scheme (where each transmitter is assigned a code) to allow multiple access. With the help of Multiple access several signals can be multiplexed over the same physical channel.

Each user in a CDMA system uses a different pseudo-random digital sequence to modulate their signal. As it uses spread spectrum technique, so the modulated signal has a much higher data bandwidth than the data being communicated.

Categories Of CDMA :-

  • Synchronous (orthogonal codes) and
  • Asynchronous (pseudorandom codes)
