    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.

    Abstract: A comparator unit is used to compare an actual transmission time signal with a nominal transmission time signal and to produce a difference signal from the discrepancy, from which difference signal a correction signal is produced in a control unit. This correction signal is used to control a correction unit, which compresses or extends an applied input data signal, thus changing the phase angle of the output data signal so as to minimize the discrepancy between the transmission times. The discrepancy is corrected independently of the system clock, and the correction speed is set variably.

    Abstract: A hardware apparatus (10) for conditioning pilot symbols for channel estimation in a mobile radio comprises a time-division multiplexed low-pass filter unit for filtering the received pilot symbols. The time-division multiplexed low-pass filter unit comprises, between its input and its output, a feedback path which can be switched in and which can be used to implement a plurality of filter stages in a time-division multiplexed arrangement.

    Abstract: An arrangement and a method for synchronizing a signal processing apparatus with a received signal which has a characteristic signal content are disclosed. The arrangement has a first control loop which readjusts the signal processing apparatus with respect to the characteristic signal content on a content basis, and a second control loop which readjusts a flow control device in the signal processing apparatus with respect to the times at which the characteristic signal content appears, the first control loop and the second control loop being coupled such that a unique association is achieved between the position of the characteristic signal content in the received signal and the associated appearance time.

    Abstract: A sequence of unfiltered channel estimation values xk is determined in a method for calculation of filtered channel estimation values dk in radio systems. A specific set of filter coefficients is selected from two or more filter coefficient sets, with the filter coefficients being calculated on the basis of the MMSE optimality criterion for a predetermined recursive digital filter (F). The sequence of unfiltered channel estimation values is then filtered by means of this recursive digital filter (F) using the selected filter coefficients.
