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

Systems/methods of adaptively varying a bandwidth and/or frequency content of communications
TL;DR: In this article, a set of frequencies that are used to provide frequency content to elements of a waveform alphabet, used to form the transmitted waveform, is varied thus varying a frequency content of the transmitted signal.

On the performance of widely linear SC-FDE systems for underwater acoustic communication
TL;DR: This paper presents a widely linear equalizer in single carrier systems with frequency-domain equalization (SC-FDE) for underwater acoustic communications that allows the distance between transmitter and receiver for a given transmitted power to be increased while maintaining the same bit error performance in a variety of scenarios.

Polarization Division Multiplexing for SC-FDE Communications over Dispersive Optical Fibers
TL;DR: The goal of the present paper is to demonstrate how the SC-FDE system can further support polarization division multiplexing (PDM) to double the communication capacity.

Signal Acquisition and Tracking for Fixed Wireless Access Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing
TL;DR: This thesis is an attempt to provide a holistic solution to the receiver implementation for the broadband fixed wireless access (BFWA) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems.

Single-carrier frequency domain equalization for broadband cooperative communications
TL;DR: This paper investigates single carrier frequency-domain equalization (SC-FDE) for distributed space-time block codes (D-STBC) in a relay-assisted transmission scenario over frequency-selective fading channels and shows that the smaller of the multipath diversity orders experienced in S rarr R and R rarr D links becomes the performance bottleneck for the relays.

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.
