Adaptive Prediction of Channels with Sparse Features in OFDM Systems by Changwei Lv, Shujuan Hou, Wenbo Mei

“…We also compare the proposed prediction method with the classical frequency domain method realized at each OFDM subcarrier and demonstrate that our method increases the prediction accuracy and reduces the computational complexity. Simulations on the physical channel model verify the performance of the proposed method.…”
