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

Widely linear MMSE precoding and equalization techniques for SC-FDE systems
TL;DR: Simulation results show that together with the error performance gain, these SC-FDE systems have lower sensibility to the feedback filter length in systems using decision-feedback equalizers, and in Tomlinson-Harashima precoded systems, the performance gain is observed even with channel estimation/channel state information errors.
Performance evaluation and parameter optimization of MC-CDMA
Mamoun Guenach,Heidi Steendam +1 more
TL;DR: In this paper, the sensitivity of MC-CDMA performance to the guard interval and the number of carriers for a given system bandwidth was investigated in different environments, and closed form expressions of the useful and different interference powers after Maximum Ratio Combining (MRC) and despreading were derived.

Robust and improved channel estimation for OFDM systems in frequency selective fading channels
TL;DR: In this article, an improved and robust channel estimation method for OFDM mobile communication systems based on the use of pilot subcarriers is presented, where an inter-path interference cancellation (IPIC) method is used to estimate the channel multipath time delays.

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.

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.
