In this paper we consider an SC-FDE (Single Carrier Frequency-
Domain Equalization) block transmission with residual frequency
errors. We employ a frequency-domain iterative DFE
(Decision Feedback Equalization) denoted by Iterative Block-
Decision Frequency Equalization (IB-DFE), which is combined
with a Decision-directed (DD) Carrier Frequency Offset
(CFO) estimator. This estimator produces a CFO estimate
plus compensation within each iteration of the equalizer. We
develop a model to predict the performance of IB-DFE receivers
with joint detection and carrier frequency synchronization.
Likewise, we propose a graphical tool allowing to
predict the number of iterations needed to reach a given Bit
Error Rate (BER) and the value of the BER for each iteration.
