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

Receiver Design for Mobile OFDM with Application to DVB-H
TL;DR: A low-complexity ICI suppression and channel estimation scheme for DVB-H systems is proposed and simulation results demonstrate that the proposed scheme is robust to mobility and can be employed efficiently in a DVb-H system.

Application of angular diversity in OFDM systems
Wee Teck Ng,V.K. Dubey +1 more
TL;DR: Simulation results show that angular diversity in OFDM systems can provide significant improvement as compared to using only single beamforming, and multiple beamforming using uniform linear arrays (ULA) is used to reduce Doppler spread and exploit the advantage of diversity.

STBC for uplink single-carrier CDMA with equalization in the frequency domain
TL;DR: A new air interface that combines SC-CDMA with space time block coding (STBC) across multiple transmit antennas in order to robustify the link is proposed and the complexity of the joint detector is significantly reduced.

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.
