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

On the design of multidimensional signal sets for OFDM systems
D.L. Goeckel,G. Ananthaswamy +1 more
TL;DR: Numerical results are presented which suggest that the nonstandard multidimensional signal sets matched to the OFDM framework can provide an attractive alternative to a standard OFDM system in terms of required average transmitted SNR versus receiver complexity and the system yields a modest reduction in PMEPR versus a standard OfDM system.

Use of supplemental assignments to decrement resources
TL;DR: In this article, the authors describe a system and methodologies that facilitate dynamically supplementing or decrementing resource assignments to mobile devices in a wireless network environment without requiring transmission of replacement assignments.

OFDM Blind Parameter Identification in Cognitive Radios
H. Ishii,Gregory W. Wornell +1 more
TL;DR: The algorithm is essential for two systems: first, cognitive radios that change fundamental parameters frequently to provide high throughput and high quality of services; and, second, radio monitoring systems that detect illegal signals transmitted by unlicensed devices.
Journal ArticleDOI
Block channel equalization in the frequency domain
TL;DR: Performance results for both uncoded and coded phase-shift keying transmissions show the efficacy of the proposed equalization techniques and their superiority over other existing frequency-domain equalization strategies.

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.
