Exempel på hur man kan använda FDMA i en mening

• For example, Daniel Minoli (2009) identifies five principal types of multiple-access schemes: FDMA, TDMA, CDMA, SDMA, and random access.
• In FDMA, all users share the satellite transponder or frequency channel simultaneously but each user transmits at single frequency.
• As early as the 1960s, NASA's Application Technology Satellite (ATS) and Advanced Communications Technology Satellite (ACTS) programs prototyped many of the technologies used on TDRSS and other commercial communications satellites, including frequency division multiple-access (FDMA), three-axis spacecraft stabilization and high-performance communications technologies.
• To distinguish signals from several different transmitters, frequency-division multiple access (FDMA, used by analog and D-AMPS systems), time-division multiple access (TDMA, used by GSM) and code-division multiple access (CDMA, first used for PCS, and the basis of 3G) were developed.
• In multiple access channels (code-division multiple access (CDMA), frequency-division multiple access (FDMA), time-division multiple access (TDMA)), beamforming is necessary and sufficient.
• 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.
• DAMA and PAMA are related only to channel/resource allocation and should not be confused with the multiple access/multiplexing methods (such as FDMA frequencies, TDMA slots, CDMA codes, or others) intended to divide a single communication channel into multiple virtual channels.
• Disaster and evacuation information from government ministries and local governments, EEW and Tsunami Warning from JMA, and J-Alert from FDMA.
• DMR (digital mobile radio), and dPMR (digital private mobile radio) are more recent ETSI-standards for digital mobile radio using two-slot TDMA and FDMA respectively.
• CT2 is a digital FDMA system that uses time-division duplexing technology to share carrier frequencies between handsets and base stations.
• In 2011, Motorola deployed ASTRO 25 systems with P25 Time Division Multiple Access (TDMA) trunking to double the voice capacity of Frequency Division Multiple Access (FDMA) technology.
