Title
A blind linear smoothing method for OFDM systems without cyclic prefix
Abstract
A linear smoothing based blind channel estimation method for orthogonal frequency-division multiplexing (OFDM) systems over time-dispersive channel is proposed. The proposed method does not require a cyclic prefix and thus leading to higher spectral efficiency. By exploiting the block Toeplitz structure of the channel matrix, the proposed blind estimation method performs satisfactorily with very few received OFDM blocks. Therefore, it is attractive for channel estimation under fast changing channel environment. Computer simulations demonstrate the superior performance of the proposed algorithm over methods reported earlier in the literature.
