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.

Adaptive single-carrier transmission using QRM-ML block signal detection

TL;DR: It is shown that the introduction of an unequal bit loading to SC block transmission using QRM-MLBD can achieve almost the same BER performance as the conventional QRM -MLBD while significantly reducing the required number M of surviving path in the M-algorithm.

Performance of joint MMSE-THP/Pre-FDE for single-carrier transmissions in a frequency-selective channel

TL;DR: To further improve the BER performance, THP is optimized based on the minimum mean square error (MMSE) criterion and a joint MMSE-THP/pre-FDE is proposed.

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.
