BEM-based iterative EKF channel estimation using superimposed pilot for OFDM system in high-speed railway
TL;DR: The proposed iterative extend Kalman filter (iEKF) channel estimation method based on basis expansion model (BEM) for orthogonal frequency division multiplexing (OFDM) system has better estimation accuracy, robustness and higher throughput under low signal to noise ratio (SNR) condition in high-speed mobile scenes compared with traditional estimation methods.
