On companding techniques for PAPR reduction in DCT SC-FDMA system in the presence of CFOs
Alexandria Engineering Journal, 2023 In the single carrier frequency division multiple access (SC-FDMA) system, the use of discrete cosine transform (DCT) instead of discrete Fourier transform (DFT) has shown improved bit error rate (BER) performance.

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-

Scheduling for virtual MIMO in Single Carrier FDMA (SC-FDMA) system
2010 International Conference on Information and Communication Technology Convergence (ICTC), 2010 In this paper, we consider a joint frequency-domain scheduling and user-pairing problem for virtual MIMO in SC-FDMA system, e.g., 3GPP-LTE. Due to the subcarrier adjacency constraint inherent to SC-FDMA, its complexity becomes unmanageable. We propose a greedy heuristic algorithm for PF scheduling to deal with the complexity in this joint problem.

Performance Analysis of a Modified SC-FDMA-DSCDMA Technique for 4G Wireless Communication
Journal of Computer Networks and Communications, 2014 Single-carrier FDMA (SC-FDMA) is becoming more and more popular in multiuser communication because of its lower PAPR value. Apart from this, many other hybrid access techniques have also been explored in the literature for application to 4G wireless ...
