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

MMSE-FDE Based on Estimated SNR for Single-Carrier Block Transmission (SCBT) in Multi-Gbps WPAN (IEEE 802.15.3c)
TL;DR: SCBT with MMSE-FDE (aided by SNR estimation), based on a simple signal-to-noise ratio (SNR) estimation method for single-carrier block transmission (SCBT) over multi-path fading channels is very promising for realizing data rates of multi-Gbps in wireless personal area network (WPAN).

Single carrier frequency domain equalization with noise prediction for broadband wireless systems
Yu Zhu,Khaled Ben Letaief +1 more
TL;DR: It is demonstrated that the performance complexity tradeoff of the proposed scheme can be obtained by only changing the order of the noise predictor, in contrast to the conventional FD-DFE scheme where both the ME and the time domain feedback filter must be modified simultaneously.

Equalizer for single carrier fdma receiver
TL;DR: In this article, a method of equalizing a received signal compensates for frequency selectivity of the communication channel taking into account channel estimation errors is proposed, which comprises generating channel estimates for the received signal, computing filter weights for an equalizer based on said channel estimates and a covariance of the channel estimation error, and filtering the received signals using the computed filter weights.

Fast-Converging Blind Adaptive Channel-Shortening and Frequency-Domain Equalization
TL;DR: A unit-tap constraint is used to manipulate existing algorithms into a framework analogous to the recursive least squares algorithm, and adaptation rules for blind and semiblind frequency domain equalizers for SCCP receivers are developed.

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
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.
