    The invention is based on an adaptive prediction algorithm which can be controlled by a speed coefficient in order to work at a first adaptation speed and with a first degree of precision of adaptation and degree of precision of prediction in the event that the speed coefficient has a first value and with a second degree of precision of adaptation, which is lower than the first, and with a degree of precision of prediction, which is higher than the first in the event that the speed parameter has a second value, wherein the periods of adaptation occurring after the reset times during which the prediction errors are initially increased as a result of the not yet adapted prediction coefficients, are reduced by initially adjusting the speed parameter to the first value(42) and after a while adjusting it to the second value(50). When the speed parameter is readjusted to the second value after a specific time period after the reset times, the prediction errors and the residuals that are to be transferred are optimized or smaller than with the first speed parameter value.
