What is CDMA?- CDMA (Code Division Multiple Access) is a multiplexing technique based on spread spectrum approach.
- This allows several users to share a bandwidth of frequencies.
- In this, a special coding scheme is used where each transmitter is assigned a code to allow multiple users to be multiplexed over the same physical channel.
- It refers to any several protocols which is used in second and third generation wireless communication.
- It employs analog to digital conversion in combination with spread spectrum technology.
