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

Adaptive Decision Feedback Channel Estimation with Periodic Phase Correction for Frequency-Domain Equalization in DS-CDMA Mobile Radios
Le Liu,Fumiyuki Adachi +1 more
TL;DR: Adapt DF (ADF)-MMSE-CE is proposed, in which the DF filter coefficient is adapted to changing channel conditions based on a recursive least square (RLS) algorithm, and the scheme is very robust against fast fading.

Pseudo block coded single-carrier frequency-domain equalization transmission
TL;DR: This paper evaluates, by computer simulation, the average bit error rate (BER) performance of PBCSC-FDE and shows that its achievable BER performance is superior to a 2-step decoding which performs FDE and hard decision block decoding separately.
