1. Narrowband orthogonal frequency division multiplexing power line communicationtransceivers for G3-PLC networks. 2. The real definition of " Frequency division multiple access " is available at FDMA. 3. FDMA is distinct from frequency division duplexing ( FDD ). 4. NIST's Time and Frequency Division provides free software at www . bldrdoc . gov. 5. Scalable Orthogonal Frequency Division Multiple Access ( SOFDMA ) technology. 6. This is called frequency division multiplexing ( FDM ). 7. At the same time as AM radio began, carrier frequencies, called " frequency division multiplexing ". 8. In addition, modulation has the advantage that it may use frequency division multiplexing ( FDM ). 9. The Time and Frequency Division is part of the NIST's Physics Laboratory, based in Gaithersburg, Maryland. 10. There, they developed his theory into a technology called vector orthogonal frequency division multiplexing, or VOFDM.
