General pilot-aided scheme for OFDM reception in fast varying channels
In high mobility scenarios, the channel variation over an OFDM symbol period destroys subcarrier orthogonality, and results in intercarrier interference (ICI). Recently, a piece-wise linear model has been proposed to mitigate ICI by approximating the channel variation over an OFDM symbol by linear m...
