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

Description of a frequency and symbol synchronisation system for OFDM signals and simulation results in a multipath radio channel
G. Santeolla,F. Andrea +1 more
TL;DR: The phase discriminator and frequency discriminator for, respectively, the symbol and frequency synchronization loop are described and simulation results in presence of Rayleigh multipath channel are reported.
Advanced OFDM systems for terrestrial multimedia links
TL;DR: An extended OFDM system is proposed that offers variable bandwidth, improved protection to shadow and multipath fading and enhanced robustness thanks to the insertion of deep time-interleaving coupled with a powerful turbo codes concatenated error correction scheme.

Performance enhancement of multicarrier CDMA systems impaired by chip timing jitter
L. Tomba,W.A. Krzymien +1 more
TL;DR: It is shown that the presence of a timing error less than about 20% of the sampling period can be modelled by an equivalent additional amount of additive white Gaussian noise, which is useful for getting analytical or semi-analytical formulas for the error probability.

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.
