  author={Huang Chang Lee and Chao-Wei Chen and Shyue-Win Wei},
  journal={IEEE Transactions on Communications},
A time-varying channel estimation method for orthogonal frequency division multiplexing (OFDM) systems is presented. The presented channel estimation method employs two training symbols in combination with polynomial fitting, thus obtaining accurate estimation results under a large normalized Doppler frequency.
