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 equalization technique for orthogonal frequency-division multiplexing systems in time-variant multipath channels
TL;DR: A simple frequency-domain equalization technique which can compensate for the effect of ICI in a multipath fading channel in orthogonal frequency division multiplexing systems is proposed.

Broadband wireless access solutions based on OFDM access in IEEE 802.16
I. Koffman,V. Roman +1 more
TL;DR: This work overviews the work of the one of the IEEE 802.16 standard subcommittee projects that deals with a BWA solution based on OFDM access (OFDMA) aiming at the most challenging NLOS scenarios.

Low-complexity equalization of OFDM in doubly selective channels
TL;DR: This work proposes a novel two-stage equalizer whose complexity (apart from the FFT) is linear in the OFDM symbol length, and results indicate that the equalizer has significant performance and complexity advantages over the classical linear MMSE estimator in doubly selective channels.

Channel estimation for OFDM transmission in multipath fading channels based on parametric channel modeling
TL;DR: It is demonstrated that the use of the parametric channel model can effectively reduce the signal subspace dimension of the channel correlation matrix for the sparse multipath fading channels and, consequently, improve the channel estimation performance.
Journal ArticleDOI
Single-carrier frequency domain equalization
TL;DR: This paper present an alternative promising approach to ISI mitigation by the use of single-carrier (SC) modulation combined with frequency-domain equalization (FDE).

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.

Data Transmission by Frequency-Division Multiplexing Using the Discrete Fourier Transform
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
TL;DR: A frequencydependent quadrature model is proposed whose parameters are obtainable from single-tone measurements and is shown to fit measured data very well.

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.
