Abstract
A method and system for determining the average long-term is described, in which a short-term power of a segment of the input signal is determined and a data sequence is produced that is contained in the segment and with which the input signal is modulated. A reference signal is produced by modulation with the data sequence at a predetermined reference control factor of a modulator, in which a long-term power of the reference signal corresponds to the reference control factor, and a short-term power of the reference signal within the segment is determined. A correction value is determined by comparing the short-term power of the reference signal with the long-term power of the reference signal corresponding to the reference control factor; and the short-term power of the segment of the input signal is corrected based on the correction value in order to obtain the long-term power of the input signal.
