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.
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.
Removable User Identity Module (R-UIM, usually pronounced as "R-yuim") is a card developed for cdmaOne/CDMA2000 ("CDMA") handsets that extends the GSM SIM card to CDMA phones and networks. To work in CDMA networks, the R-UIM contains an early version of the CSIM application. The card also contains SIM (GSM) application, so it can work on both ...

smart matrix array for combine input signal gain separated them with filters and different types of output multiplexed schemes are used for approach to multiple users for example CDMA, FDMA, WCDMA, TDMA, and ODMA. [clarification needed] Such way calls and network services are approach and authenticate to unique subscriber. core network link ...
Access Authentication in CDMA networks for telecommunications and computing provide network access for a mobile device. Specific methods such as CAVE-based Authentication (IS-95/1xRTT), and A12 Authentication are possible. The serving network provides the mobile device access authentication mechanism.
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.
The Preferred Roaming List (PRL) is a database residing in a wireless (primarily CDMA) device, such as a cellphone, that contains information used during the system selection and acquisition process. In the case of R-UIM -based CDMA devices, the PRL resides on the R-UIM .
