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.

Efficient Computation of the Feedback Filter for the Hybrid Decision Feedback Equalizer in Highly Dispersive Channels

TL;DR: In the paper it is proposed to adopt the (cepstral) method for spectral factorization due to Kolmogoroff, which can be efficiently implemented by using the fast Fourier transform (FFT), and the application of the method is considered for highly dispersive channels.

Layered space-time receivers for single-carrier transmission with iterative frequency-domain equalization

TL;DR: This work introduces two new iterative frequency-domain BLAST receivers for highly dispersive channels, and considers the use of single carrier modulations with frequency domain equalization (FDE) techniques, which are known to be excellent candidates for severely time-dispersive channels while maintaining a low complexity.

Iterative Joint PIC and 2D MMSE-FDE for Turbo-coded HARQ with SC-MIMO Multiplexing

TL;DR: The proposed frequency-domain iterative parallel interference cancellation (PIC) for SC-MIMO multiplexing is used, 2 dimensional minimum mean square error (2D MMSE)-FDE is used instead of ID MMSE-FDE in each iteration and the achievable bit error rate (BER) and throughput performance of HARQ in a frequency-selective Rayleigh fading channel is investigated.

Error Probability Analysis of Interleaved SC-FDMA Systems Over Nakagami- $m$ Frequency-Selective Fading Channels

TL;DR: This paper presents an analytical study of the average bit error probability (ABEP) for interleaved single-carrier frequency-division multiple-access systems over independent but not necessarily identically distributed Nakagami-m fading channels with fading parameters {m} being integers when either zero-forcing (ZF) or minimum-mean-square-error (MMSE) frequency-domain equalization (FDE) is applied.

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.

BER sensitivity of OFDM systems to carrier frequency offset and Wiener phase noise

TL;DR: In this contribution the transmission of M-PSK and M-QAM modulated orthogonal frequency division multiplexed (OFDM) signals over an additive white Gaussian noise (AWGN) channel is considered and the degradation of the bit error rate is evaluated.
