Code Division Multiple Access (CDMA)

Code Division Multiple Access (CDMA) Code Division Multiple Access (CDMA) is a digital technique for sharing the frequency spectrum. Multiple users are assigned radio resources using spread Spectrum techniques. Although all users are transmitting in the same RF band, individual users are separated from each other via the use of orthogonal codes. CDMA is based on proven Spread Spectrum communications technology”  There are several CDMA implementations...
