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

Frequency domain equalization for single-carrier broadband wireless systems
TL;DR: This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions and discusses similarities and differences of SC and OFDM systems and coexistence possibilities, and presents examples of SC-FDE performance capabilities.

Single carrier FDMA for uplink wireless transmission
TL;DR: Among the possible subcarrier mapping approaches, it is found that localizedFDMA (LFDMA) with channel-dependent scheduling (CDS) results in higher throughput than interleaved FDMA (JFDMA), however, the PARR performance of IFDMA is better than that of LFDMA.

The AN/GSC-10 (KATHRYN) Variable Rate Data Modem for HF Radio
M. Zimmerman,A. Kirsch +1 more
TL;DR: The AN/GSC-10 (KATHRYN) is a new modem equipment for digital data transmission on HF radio circuits that provides a wide range of signal redundancy and data rate to allow optimum performance over the correspondingly widerange of propagation conditions characteristic of HF radio.

Performance of an RCPC-coded OFDM-based digital audio broadcasting (DAB) system
TL;DR: A static code design with unequal error protection (UEP) is presented that also takes auxiliary data services into account and emphasis is on the use of source-adapted channel coding with rate-compatible punctured convolutional (RCPC) codes.

Selectrive Fading Limitations of the Kathryn Modem and Some System Design Considerations
TL;DR: In this paper, the error probability limitations caused by multipath and Doppler smear in the Kathryn modem, a new HF modem of considerable current interest, were investigated. And the effects of diversity combining are studied in all cases.
