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

Optimization of OFDM on frequency-selective time-selective fading channels
Heidi Steendam,Marc Moeneclaey +1 more
TL;DR: This work investigates how various parameters, such as the number of carriers, the guard time length and the sampling offset between receiver and transmitter, affect the system performance and determines the optimum values of the above parameters, which minimize the degradation of the signal-to-noise ratio at the input of the decision device.

Frequency domain equalization with tomlinson-harashima precoding for single carrier broadband MIMO systems
Yu Zhu,Khaled Ben Letaief +1 more
TL;DR: It will be shown that by applying channel prediction and THP compensation techniques such detrimental effects can be greatly reduced in the conventional FDE MIMO schemes.

A fast burst synchronization scheme for OFDM
TL;DR: A burst synchronization scheme with a short preamble signal for high data rate wireless LAN systems that use orthogonal frequency division multiplexing (OFDM) and automatic frequency control and symbol timing detection is proposed.

An Iterative Receiver for OFDM With Sparsity-Based Parametric Channel Estimation
TL;DR: In this paper, a sparsity-based parametric channel estimation based iterative receiver is proposed to pass soft information between the channel estimation and data decoding stages, and the receiver performs very close to the perfect channel state information bound for all SNR values.

Study of multiple access schemes in 3GPP LTE OFDMA vs. SC-FDMA
TL;DR: An overview of both OFDMA and SC-FDMA is given and their dependence of symbol error rate (SER) on signal to noise ratio (SNR) in flat fading Rayleigh channel, and their Peak-to-Average Power ratio (PAPR) curves are shown.

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

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.
