TLDR
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency- domain equalization, and introduces coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving.Abstract:
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency-domain equalization. The carrier synchronisation issue is dealt with before the authors introduce coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving. >read more

Single-carrier frequency-domain equalization for multi-relay cooperative systems with relay selection
Homa Eghbali,Sami Muhaidat +1 more
TL;DR: To overcome the loss in bandwidth efficiency due to the deployment of orthogonal DSTBC, several relay selection strategies for D-SC-FDE over frequency selective channels are presented and investigated.

CP-DSSS: An OFDM Compatible Variable Rate Modulation for 5G and Beyond
TL;DR: It is shown that the channel model of CP- DSSS reduces to that of a cyclic prefixed block-wise single carrier modulation (CP-SCM), which allows CP-DSSS power spectral density to drop to an arbitrarily low level, facilitates it coexistence as a secondary waveform in a network of primary users.

Multi-user transmissions
TL;DR: In this article, a plurality of weights for orthogonal frequency division multiplexing (OFDM) transmission of data associated with multiple nodes and/or users is discussed. But the authors focus on the MIMO-capable node.

Robust frequency-domain equalization against doubly selective fading for single-carrier STBC time-division duplex transmission
TL;DR: The proposed multi-block (MB)-frequency-domain equalization (FDE) for SC-STBC-TDD transmission in a high mobility environment uses jointly optimized multiple FDE weight matrices, each associated with each signal block in a STBC codeword.

Multicarrier modulation for data transmission: an idea whose time has come
TL;DR: The general technique of parallel transmission on many carriers, called multicarrier modulation (MCM), is explained, and the performance that can be achieved on an undistorted channel and algorithms for achieving that performance are discussed.

Analysis and Simulation of a Digital Mobile Channel Using Orthogonal Frequency Division Multiplexing
TL;DR: The analysis and simulation of a technique for combating the effects of multipath propagation and cochannel interference on a narrow-band digital mobile channel using the discrete Fourier transform to orthogonally frequency multiplex many narrow subchannels, each signaling at a very low rate, into one high-rate channel is discussed.

Performance of an Efficient Parallel Data Transmission System
TL;DR: A parallel quadrature AM data transmission system with a number of overlapping channels, each carrying a signaling rateb, spacedb/2apart in frequency appears to be a promising technique for achieving good performance at high information rates over bandlimited dispersive transmission media.
