Frequency-domain precoding for single carrier frequency-division multiple access [PDF]
IEEE Communications Magazine, 2009 At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

Non-Orthogonal Frequency Division Multiple Access [PDF]
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 This paper proposes a frequency-domain multiple user access scheme termed non-orthogonal frequency division multiple access (NoFDMA), which maintains the same data rate per user while allowing more users to access via non-orthogonal user overlapping in a given spectral band.

New Transceiver Designs for Interleaved Frequency-Division Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2020 This paper puts forth a class of new transceiver designs for interleaved frequency division multiple access (IFDMA) systems. These transceivers are significantly less complex than conventional IFDMA transceiver. The simple new designs are founded on a key observation that multiplexing and demultiplexing of IFDMA data streams of different sizes are ...
