Abstract

The invention relates to an apparatus for preprocessing of pilot symbols for channel estimation. The pilot symbols are transmitted from a base station and are received by a mobile radio, and are available in the mobile radio. The apparatus includes a low-pass filter apparatus for filtering the received pilot symbols, with a setting of the low-pass filter apparatus depending on the relative speed of the mobile radio with respect to the base station.
