Question
CDMA is a communication technique that allows multiple users to share the same frequency band simultaneously by using unique codes to differentiate their transmissions. Unlike TDMA and FDMA, CDMA does not divide the spectrum into separate time slots or frequency bands. Instead, each user's data is encoded with a specific code, and all users transmit their encoded data simultaneously over the same frequency range. The receiver, which knows the code of the user it's listening to, can then decode the intended signal by applying the corresponding code. CDMA is known for its ability to mitigate interference and is commonly used in technologies like WCDMA (3
- G and certain 4G and 5G networks.
