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

Multiple-access interference suppression for OFDM systems based on Doppler shifts
TL;DR: It is shown that this can be achieved with multicarrier CDMA (MC-CDMA), and the relationship between the interference suppression capability and the Doppler shifts is studied in terms of signal-to-interference ratio (SIR).

Error Rate Analysis of Multi-carrier Modulation Using Differentially Encoded and Detected 16 DE-APSK under Rician Fading Channels

Impact and compensation of sample clock offset on up-link SC-CDMA
TL;DR: It is shown that clock offset leads to an unacceptable degradation of the performance if it is not compensated, and it is demonstrated that the compensation can be done at the receiver.

Threshold-Free Erasure Decoded Multicarrier Local Transmission over Multipath Channels
TL;DR: The results indicate that the erasure decoding based on relative (threshold-free) measures clearly promises an improved performance of the MCM system.

Systems/methods of adaptively varying a spectral content of communications
TL;DR: In this paper, the spectral content of a baseband waveform is varied and a measure of the BS waveform whose spectral content has been varied is used by a transmitter in order to convey information.

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.
