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

A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
TL;DR: A computationally efficient, pilot-aided linear minimum mean-square-error (MMSE) time-domain channel estimation algorithm for OFDM systems with transmitter diversity in unknown wireless fading channels and the effect of a modelling mismatch on the estimator performance is analyzed.

Blind channel identification for multirate precoding and OFDM systems
TL;DR: Methods of blind channel estimation for more general transform modulations are supported in this framework and some redundancy, independent of the channel memory, is shown to be necessary for OFDM and other orthonormal transformation systems for blind channel identification.

The MAI Mitigation Scheme for OFDM-based Asynchronous Networks over Multi-Cell Environments
TL;DR: This paper investigates the problem of MAI (multiple access interference) occurrence when timing misalignment occurs in the downlink channel of OFDM-based networks and proposes an adaptive carrier allocation scheme that is very effective in reducing MAI for asynchronous multi-cell network.

OFDM systems with multiple trellis coded modulation
TL;DR: An orthogonal frequency division multiple access (OFDM) system in which MTCM (multiple trellis coded modulation) is applied to a set of multiple subcarriers in order to enlarge the summation of the Euclidean distance and the product distance is 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.

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.
