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

Diversity order in ISI channels with single-carrier frequency-domain equalizers
Ali Tajer,Aria Nosratinia +1 more
TL;DR: In this article, the authors analyzed the diversity gain achieved by single-carrier frequency-domain equalizers (SC-FDE) in frequency selective channels, and uncovered the interplay between diversity gain d, channel memory length, transmission block length L, and the spectral efficiency R. They showed that for the class of minimum mean-square error (MMSE) SCFDE receivers, for rates R? log L/? full diversity of d =?+ 1 is achievable, while for higher rates the diversity is given by d = [2-R L + 1.

Performance of Single-Carrier Block Transmissions Over Multipath Fading Channels With Linear Equalization
TL;DR: It is proven that when minimum mean-squared-error (MMSE) equalization is adopted, ZP transmission outperforms CP transmission and uncoded orthogonal frequency-division multiplexing (OFDM) on the average over random channels.

TL;DR: Historic developments in orthogonal frequency-division multiple access (OFDMA) was adopted by the WiMAX Forum for mobile WiMAX systems and more recently by the 3GPP for the downlink of Long Term Evolution (LTE) systems, while single-carrier FDMA was adopted for the uplink of LTE.

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.
