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

An uncoded BER comparison between DFE-SCCP and OFDM using a convex analysis framework
TL;DR: This article aims to establish a theoretical performance comparison between the Single Carrier with Cyclic Prefix equalized with a Decision Feedback Equalizer (DFE) and the Orthogonal Frequency Division Multiplexing (OFDM) systems.

A Unified Approach to Reduced-Redundancy Transceivers: Superfast Linear and Block-Iterative Generalized Decision Feedback Equalizers
TL;DR: It is argued that, under a one-tap block decision feedback, transmitted redundancy can be reduced below the minimum |(L-1)/2| samples allowed in the linear case, where L is the channel length, even down to zero-redundancy, with improved BER performance.

Filter Bank Based Frequency-Domain Equalization with Noise Prediction
TL;DR: A hybrid frequency-time domain equalizer, which utilizes FB based equalizer for the feedforward part and a noise predictor (NP) for the feedback, able to provide significant performance enhancement over the DFE structure where the decoding is after the feedback loop.

An application of amplitude and phase predistortion to OFDM systems
TL;DR: The above technique is shown to provide a major enhancement in power efficiency in comparison with the unprotected system, as well as a nonnegligible gain over an alternative linearization strategy, identified as minimum mean square error (MMSE) predistortion.

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.

Stephen B. Weinstein,P. Ebert +1 more
TL;DR: The Fourier transform data communication system is described and the effects of linear channel distortion are investigated and a differential phase modulation scheme is presented that obviates any equalization.

Frequency-Independent and Frequency-Dependent Nonlinear Models of TWT Amplifiers

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.
