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

DFT-Spread-OFDM-Based Chirp Transmission
TL;DR: The proposed framework offers a new way to efficiently synthesize chirps that can be used in Internet-of-Things (IoT), dual-function radar and communication (DFRC) or wireless sensing applications with existing DFT-s-OFDM transceivers.

Single-carrier frequency-domain equalization for space-time-coded transmissions over broadband wireless channels
TL;DR: This work proposes a scheme like that of S. Alamouti for combining space-time block-coding with single-carrier frequency-domain equalization that achieves significant diversity gains at low complexity over frequency-selective fading channels.

Second-Order Cyclostationarity of Cyclically Prefixed Single Carrier Linear Digital Modulations with Applications to Signal Recognition
TL;DR: An algorithm is proposed for the recognition of CP-tSCLD against SCLD and orthogonal frequency division multiplexing (OFDM) signals that obviates the need for signal pre-processing tasks, such as symbol timing, carrier and waveform recovery and estimation of signal and noise powers.

Iterative receiver with joint detection and channel estimation for OFDM system with multiple receiver antennas in mobile radio channels
TL;DR: The main feature of the proposed scheme is to design a rather simple iterative receiver by employing a two-dimensional channel estimator in the time/frequency domain with a reduced complexity by employing an estimation filter subject to unknown channel statistics.

JingFeng Liu,Hongwei Song +1 more
TL;DR: In this paper, a data processing circuit is described that includes an analog to digital converter, an online timing loop and an offline timing loop, and each bit of the first series of data samples corresponds to the analog input at a time controlled by an updated sampling clock.
