A method and the corresponding device for improving channel estimation in an OFDM system are presented. The invention involves a refining digital filter (150) that is applied to the pilot-based channel response estimate to obtain a refined estimate. The filter coefficients are adaptively changed (160) in order to reduce a variance (or an average) of the error on the coarse channel estimations on pilot tones.

Abstract
A method and the corresponding device for improving channel estimation in an OFDM system are presented. The invention involves a refining digital filter (150) that is applied to the pilot-based channel response estimate to obtain a refined estimate. The filter coefficients are adaptively changed (160) in order to reduce a variance (or an average) of the error on the coarse channel estimations on pilot tones.File in questo prodotto:
