“…In non sample-spaced multipath channels, the channel impulse response will leak to all taps in the time domain. The improved DFT based [4] and DCT based [5,6] channel estimation methods are the two published methods used for the channel estimation in the case of non-sample spaced time delays. The improved DFT based channel estimation method uses a symmetric extension in frequency domain [7] to reduce the leakage energy problem.…”

This paper deals with the estimation of the channel in orthogonal frequency division multiplexed systems. In this paper, a new DCT-based pilot-symbol-aided channel estimation method is proposed. The energy leakage in multipath channel with non-sample-spaced time delays is eliminated here. The proposed method uses symmetric property to extend the LS estimate in frequency domain to remove the effects of non-sample spaced time delays. The computer simulation results demonstrate that the new method can reduce the leakage energy efficiently, and the performance of the new channel estimation method is better than the LS and improved DFT algorithm.
