Abstract
In this work, we address the problem of channel estimation in multicarrier communications by means of the Type-III even discrete cosine transform (DCT3e). We present a novel efficient procedure based on using the DCT3e both at the transmitter and the receiver. The proposed approach does not require adding any redundancy or knowing the exact length of the channel’s impulse response. It suffices to use any symmetric training sequence at the transmitter with enough leading and tail zeros. We demonstrate that an accurate estimation of the channel’s impulse response can be attained, and illustrate the good behavior of the proposed scheme using ITU-T pedestrian channel B.
