CSI RefineNet: A Soft Data-Aided Iterative Receiver for High-Mobility OFDM Systems

A CSI RefineNet receiver is proposed, where the CSI is iteratively refined using soft symbol decisions in a data-aided manner, and achieves superior BER performance and strong robustness under different velocities, modulation orders, and pilot spacing configurations in high-mobility OFDM systems.
