Abstract:
1. Method for performing a quality assessment of a signal transmission link having non-linear distortion, in which a predetermined test signal is transmitted from a transmitter to a receiver, the level of the received signal is first adjusted in the receiver and then a global quality assessment is performed by means of a predetermined comparison method, characterized in that, for the purpose of adjusting the level, a) a local quality assessment based on the predetermined comparison method is performed in a predetermined number of different, predefined time windows (V b) at least one window having adequate local transmission quality is determined, in that c) the ratio of the signal level of the test signal to the signal level of the received signal is calculated in at least one of the windows determined, and in that d) the level of the total received signal is set on the basis of said ratio.
