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...
