RECURSIVE TIME-FREQUENCY CHANNEL ESTIMATION

摘要

The present invention relates to a method, apparatus, and computer program product for estimating a channel of a multi-carrier transmission by splitting an interpolation or extrapolation or smoothing of estimates into a frequency domain part (14) and a time domain part (15), wherein the channel estimation unit is configured to use for both the frequency domain part and the time domain part respective recursive filters, and wherein at least one of the recursive filters is adapted (13) to channel conditions of the multi-carrier transmission.
