Frequency domain equalization for single-carrier broadband wireless systems

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.

Efficient Transmitter and Receiver Designs for SC-FDMA Based Heterogeneous Networks

TL;DR: The results show that the proposed schemes are robust to both inter-system and inter-carrier interferences and thus are able to efficiently separate the macro- and small-cells spatial streams under limited information exchange.

Cyclic delay diversity with frequency domain turbo equalization for uplink fast fading channels

TL;DR: Simulation results show that the performance of proposed CDD with frequency domain turbo equalization for single carrier transmission approaches the corresponding orthogonal spacetime block coding (STBC) system in slowly fading channels without any data rate loss, and considerably outperforms the STBC system in fast fading channels.

An Analytical Approach for Finite Block Length Performance Analysis of Turbo Frequency-Domain Equalization

TL;DR: The analytical approach in the method in deriving the equalizer curve eliminates the need for histogram generation and makes the implementation of this method remarkably simpler than that of the EXIT chart.

Secure communication in frequency selective channels with fade-avoiding subchannel usage

TL;DR: An adaptive transmission scheme in which the faded subchannels of the legitimate channel are not used for conveying information is proposed, and it is showed that while careful usage of the subch channels in frequency selective channels improves the secrecy, introducing the fade-filling noise creates an error floor for the malicious nodes.

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.
