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

Nonlinear predistortion of OFDM signals over frequency-selective fading channels
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, presented in the literature for application to OFDM.

Video Compression and Communications: From Basics to H.261, H.263, H.264, MPEG4 for DVB and HSDPA-Style Adaptive Turbo-Transceivers
TL;DR: Video Compression and Communications has been updated and condensed yet remains all-encompassing, giving a comprehensive overview of the subject, covering compression issues, coding delay, implementational complexity and bitrate.

Efficient signaling over access channel
TL;DR: In this paper, an apparatus and method for transmitting an indicator of channel quality while minimizing the use of a broadcast channel is described, and a metric of forward link geometry of observed transmission signals is determined.

Reduction of peak-to-average power ratio of OFDM signals with companding transform
TL;DR: A companding transform-based scheme for reducing peak-to-average power ratio (PAPR) of transmitted OFDM signals is proposed, achieving a significant reduction of PAPR with a low computational complexity.

Optimum Nyquist windowing in OFDM receivers
TL;DR: A closed solution for optimum window coefficients suited to this scenario is derived and can mitigate the joint effect of additive noise and intercarrier interference among subcarriers caused by the carrier frequency offset.

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.
