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

Flexible Subcarrier Allocation for Interleaved Frequency Division Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2020 Interleaved Frequency Division Multiple Access (IFDMA) and Orthogonal FDMA (OFDMA) belong to a class of signal modulation and multiple-access techniques in which information of multiple users are multiplexed and carried on subcarriers within a shared ...

Model division multiple access for semantic communications
Frontiers of Information Technology & Electronic Engineering, 2023 In a multi-user system, system resources should be allocated to different users. In traditional communication systems, system resources generally include time, frequency, space, and power, so multiple access technologies such as time division multiple ...

Performance Analysis of OFDMA and SC-FDMA
Vìsnik Nacìonalʹnogo Tehnìčnogo Unìversitetu Ukraïni Kììvsʹkij Polìtehnìčnij Ìnstitut: Serìâ Radìotehnìka, Radìoaparatobuduvannâ, 2017 The main challenge in any high-speed digital communication system is how to maximize the data rate with minimizing the bit error rate. Several techniques have been developed to achieve this point.

A novel frequency-domain implementation of Tomlinson-Harashima precoding for SC-FDMA [PDF]
, 2009 There is considerable interest in the use of single carrier frequency division multiple access (SC-FDMA) as the uplink transmission scheme in the 3GPP Long Term Evolution standard. This interest is justified by the inherent single carrier structure of SC-

New Transceiver Designs for Interleaved Frequency-Division Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2019 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 transceivers.
