2. Code-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Code-division_multiple_access

   Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.

3. Multi-carrier code-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Multi-carrier_code...

   Multi-carrier code-division multiple access (MC-CDMA) is a multiple access scheme used in OFDM-based telecommunication systems, allowing the system to support multiple users at the same time over same frequency band. MC-CDMA spreads each user symbol in the frequency domain.

4. Chip (CDMA) - Wikipedia

   en.wikipedia.org/wiki/Chip_(CDMA)

   In digital communications, a chip is a pulse of a direct-sequence spread spectrum (DSSS) code, such as a pseudo-random noise (PN) code sequence used in direct-sequence code-division multiple access (CDMA) channel access techniques.

   cdmaOne network structure. The IS-95 standards describe an air interface, [1] a set of protocols used between mobile units and the network. IS-95 is widely described as a three-layer stack, where L1 corresponds to the physical layer, L2 refers to the Media Access Control (MAC) and Link-Access Control (LAC) sublayers, and L3 to the call-processing state machine.

6. Demand Assigned Multiple Access - Wikipedia

   en.wikipedia.org/wiki/Demand_Assigned_Multiple...

   Demand Assigned Multiple Access (DAMA) is a technology used to assign a channel to clients that do not need to use it constantly. DAMA systems assign communication channels based on news issued from user terminals to a network security system.
