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

Analog single-carrier transmission with frequency-domain equalization
TL;DR: By computer simulation, the normalized mean square error (NMSE) performance is evaluated to show that analog SC-FDE achieves better NMSE performance than conventional analog signal transmission scheme.
Guest Editorial Special Issue: Multiple-Input Multiple-Output (MIMO) Communications
TL;DR: The authors show how full-rate full-diversity (FDFR) space-time block codes, developed by the authors in their previous work, can be efficiently combined with GF(2) channel coding, and provide valuable insight into the trade-off between performance and complexity involved in the choice of linear space- time block codes versus using powerful GF( 2) codes and their combination.

Low-complexity post-IFFT PAPR reduction technique for OFDM systems
Emad Alsusa,Lin Yang +1 more
TL;DR: In this paper, a low complexity post-IFFT peak-to-average power ratio (PAPR) reduction technique using dynamically selected time-domain amplitude randomizing sequences to minimise the PAPR per OFDM block is presented.

Semi-Blind Channel Estimation For Linearly Precoded MIMO-CPSC
TL;DR: In this paper, a linear preceding is introduced into MIMO-CPSC system to enhance channel estimation, and the precodings do not change the power of a precoded block.

A Reliable Uplink Control Channel Design with Complementary Sequences
Alphan Sahin,Yang Rui +1 more
TL;DR: Two schemes for uplink control channels based on non-contiguous complementary sequences (CSs) where the peak-to-average-power ratio (PAPR) of the resulting orthogonal frequency division multiplexing (OFDM) signal is always less than or equal to 3 dB are proposed.

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.
