Abstract:A robust discrete Fourier transform (DFT)-based channel estimation for burst orthogonal frequency division multiplexing (OFDM) systems is proposed in this paper. The conventional DFT-based channel estimation methods improve the performance by neglecting nonsignificant channel taps. However, the error floor occurs at high signal-to-noise when useful channel information is discarded, especially in non-sample-spaced channel. To solve this problem, we propose a modified DFTbased channel estimation method. Based on… Show more
