Abstract: Method for motion-compensated noise evaluation for mobile wireless transmission systems, in which reference symbols (14, 16) are sent out by a transmitter (1), with the features that from at least some of the reference symbols ({overscore (s)}?1, {overscore (s)}?2, {overscore (s)}?3) received in direct or indirect temporal succession in a receiver (2) a static component ({overscore (s)}avg) of the received reference symbols ({overscore (s)}?1, {overscore (s)}?2, {overscore (s)}?3) is determined by forming a statistical moment; a dynamic component ({overscore (s)}motion) of the received reference symbols ({overscore (s)}?1, {overscore (s)}?2, {overscore (s)}?3) is determined by comparing at least two directly or indirectly time-consecutive reference symbols ({overscore (s)}??, {overscore (s)}?1); from the static ({overscore (s)}avg) and the dynamic components ({overscore (s)}motion) of the reference symbols ({overscore (s)}?1, {overscore (s)}?2, {overscore (s)}?3) is computed a predicted value ({overscore (s)}

Abstract: A method and adaptive filter for processing a sequence of input data for an audio system may have the input data provided to first and second predictive filters, and the data may be delayed in time before or after the second filter. One of the predictive filters may be backward-looking while the other may be forward-looking, and the data filtered by the two predictive filters may be added to yield the output data. The input data may be delayed by a second delay, which may be less than the first delay, and the resulting delayed data may be used in determining a prediction error signal by subtracting the data filtered by the first predictive filter from the input data delayed by the second delay and by providing the resulting data to the first predictive filter. Alternatively, the prediction error signal may be determined by subtracting the output data from the input data delayed by the second delay. The prediction error signal may be provided to the two predictive filters.
