What is CDMA?
CDMA stands for Code Division Multiple Access which uses digital format. In CDMA systems several transmissions via the radio
interface take place simultaneously on the same frequency bandwidth. User data is combined at the transmitter’s side with a
code, then transmitted. On air, all
transmission get mixed. At the receiver's side the same code is used as in the transmitter’s side. The code helps the receiver to filter the
user information of the transmitter from incoming mixture of all transmissions on the
same frequency band and same time.
