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

Low-Complexity Symbol Timing Offset Estimation Schemes for OFDM Systems
TL;DR: Simulation results show that these schemes can be used to synchronize an OFDM system over AWGN and multi-path fading channels and make symbol synchronization possible, even though there is a frequency off- set in the system.

An efficient CFO estimation algorithm for the downlink of 3GPP-LTE
Feng Wang,Yu Zhu +1 more
TL;DR: This paper extends the traditional PSS correlation based scheme, and proposes a more efficient CFO estimation algorithm, which has better estimation performance in terms of normalized mean square error (MSE) and achieves a gain of around 2 dB over both additive white Gaussian noise (AWGN) channels and frequency selective fading channels.

A frequency offset estimation architecture of OFDM system in multipath Doppler spread channel
TL;DR: This work observes some algebraic properties of frequency offset and implicitly uses it to make a new frequency offset estimation scheme, which shows a promising result in Monte-Carlo simulation.

A Hybrid Time-Frequency Domain Equalizer for Single Carrier Broadband MIMO Systems
Yu Zhu,Khaled Ben Letaief +1 more
TL;DR: It is shown that the proposed FDE-NP scheme, which consists of a feedforward frequency domain equalizer and an array of time domain noise predictors (NPs), has lower complexity and achieves better performance and complexity trade-off than the conventional FDE designs.

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.
