TLDR
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.Abstract:
Broadband wireless access systems deployed in residential and business environments are likely to face hostile radio propagation environments, with multipath delay spread extending over tens or hundreds of bit intervals. Orthogonal frequency-division multiplex (OFDM) is a recognized multicarrier solution to combat the effects of such multipath conditions. This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions. SC radio modems with frequency domain equalization have similar performance, efficiency, and low signal processing complexity advantages as OFDM, and in addition are less sensitive than OFDM to RF impairments such as power amplifier nonlinearities. We discuss similarities and differences of SC and OFDM systems and coexistence possibilities, and present examples of SC-FDE performance capabilities.read more

Transmission Performance of Frequency-Domain Filtered Single-Carrier Transmission Using Frequency-Domain Block Signal Detection with QRM-MLD
TL;DR: From performance evaluation, it is shown that as the filter roll-off factor increases, the required number of surviving paths in the M-algorithm can be reduced and the achievable BER and throughput performances are improved.

New Designs for Reduced-Redundancy Transceivers
TL;DR: A new design strategy is proposed for reduced-redundancy block-based transceivers, which provides semi-blind equalization with data-selective update, in addition to the possibility of using redundant parallel equalizer structures, which are based on the use of fast Fourier transforms and one-tap equalizers.

TL;DR: The main objective of this thesis is to establish a novel single-carrier frequency-domain equalization model utilizing perfect reconstruction, orthogonal, complex modulated filter banks, and two low-complexity solutions for the equalization/decoding loop.
Equalization, Windowing and Zero Restoration for OFDM and Single-carrier Block Transmission
TL;DR: This work treats some aspects of multi- carrier modulation (MCM) and single-carrier frequency-domain equalization (SC-FDE), which are closely related block transmission schemes.
