Nettet4.3.4 Code Division Multiple Access (CDMA) Code division multiple access (CDMA) is a form of spread spectrum communications that is being used for, among other applications, some second-generation cellular phone systems (others use TDMA). The method is also known as S-CDMA, where the S stands for synchronous. Nettet4 Although the TDMA figure depicts 2-slot TDMA, 4-slot TDMA works in the same manner. Additional time slots increase the occupied bandwidth. 5 Although not developed or endorsed by a recognized Standards Development Organization, the standard is an open standard, available
