Analytical performance evaluation of a class of receivers with joint equalization and carrier frequency synchronization

In this paper we consider an SC-FDE (Single Carrier Frequency-Domain Equalization) block transmission with residual frequency errors. We employ frequency-domain iterative DFE (Decision Feedback Equalization) receivers denoted by Iterative Block-Decision Frequency Equalization (IB-DFE), which are combined with a Decision-directed (DD) Carrier Frequency Offset (CFO) estimator. This estimator produces a CFO estimate 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.
