Multiple Access

Multiple Access methods address the problem of how many users can share the same spectrum resources in an efficient manner. We distinguish between Examples of multiple access schemes are

Modern cellular phone systems inherently use some form of FDMA, but on each carrier multiple user signals are multiplexed. The latter involves TDMA (e.g. GSM or D-AMPS), CDMA (IS-95) or a combination of both (UMTS).
