CSI RefineNet: A Soft Data-Aided Iterative Receiver for High-Mobility OFDM Systems
In high-mobility orthogonal frequency division multiplexing (OFDM) systems, rapid channel variation can make the channel state information (CSI) estimated from pilots inaccurate for data subcarriers, leading to a mismatch with their effective channel. To address this issue, this paper proposes a CSI RefineNet receiver,...
