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.read more

Analytical performance evaluation of a class of receivers with joint equalisation and residual carrier frequency offset estimation
TL;DR: A frequency-domain iterative decision feedback equalisation denoted iterative block-decision feedbackequalisation (IB-DFE), which is combined with a decision-directed carrier frequency offset (CFO) estimator, which produces a CFO estimate within each iteration of the equaliser, which is used to compensate for the CFO.
