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.

Frequency-domain block signal detection with QRM-MLD for training sequence-aided single-carrier transmission

TL;DR: It is shown that TA-SC using FDBD with QRM-MLD can achieve the BER performance close to the matched-filter (MF) bound while reducing the computational complexity compared to CP-SC.

Iterative successive interference cancellation for quasi-synchronous block spread CDMA based on the orders of the times of arrival

TL;DR: An iterative successive interference cancellation (SIC) receiver is proposed, where cancellation of interfering signals is ordered according to the times of arrival (TOA) of the signals from different users, to mitigate the MUI in BS-CDMA due to quasisynchronous reception.

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.
