Verfahren zum Erfassen der Übertragungsqualität von digitalen Rundfunksignalen

摘要

The method involves evaluating the regular, sequential sequence of null symbols (2) as synchronization information on receiving the digital radio signal (DAB signal). The digital radio signal is sampled at twice the rate as the synchronization information. The energy of the sampling signal resulting from the null symbols is used as a measure of transmission quality.
