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

Adaptive equalization: transitioning from single-carrier to multicarrier systems
TL;DR: This article discusses the creation of adaptive algorithms for channel shortening, with particular attention to blind algorithms, and a return to first principles, a property restoral design philosophy is put forth and several recent property-restoral-based approaches to adaptive channelShortening are reviewed.

OFDM frequency offset estimation based on BLUE principle
TL;DR: Three frequency estimation methods based on the BLUE principle are presented and the first two methods' MSE performances are essentially the same and quite close to the Cramer-Rao lower bound for all SNR values; hence, these proposed methods are very attractive for OFDM applications.

On Performance of Vector OFDM With Linear Receivers
TL;DR: This paper investigates the performance of Vector OFDM with linear receivers, i.e., the Zero-Forcing (ZF) and Minimum Mean Square Error (MMSE) receivers, and proves that for both ZF and MMSE receivers, all the transmitted symbols have equal performance.

Frequency Diversity in Mode-Division Multiplexing Systems
Keang-Po Ho,Joseph M. Kahn +1 more
TL;DR: In this paper, the authors studied the effect of the modal gains and losses on the average and outage capacities in the regime of strong mode coupling and found that the difference between the average capacity and outage capacity is inversely proportional to the square root of a diversity order that is given by the ratio of the signal bandwidth to the coherence bandwidth.

A method and apparatus for bootstraping information in a communication system
TL;DR: In this paper, a method and an apparatus consisting of a plurality of electronic devices, each having a logic, is provided for receiving a preamble comprising frame structure parameters, extracting said frame structure structure parameters from said preambble, and determining a frame structure by demodulating said frame structures parameters.

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.
