Abstract (en)
[origin: EP1063799A1] From each demodulated signal, a channel impulse response (53) is determined. The succession in time, and amplitude of the first synchronization signals received (72, sync) are determined by comparison with a first reference synchronization signal. Amplitude peaks of the determined channel impulse response (53) are allocated to a first transmitter (S1, S2, S3). Each DAB (digital audio broadcasting) packet contains two synchronization signals. The second (71, null) with different transmitter identification, is compared in a similar process, determining second synchronization signals with the greatest agreement from a range of these signals, and attributing amplitude peaks to them. An Independent claim is included for corresponding measurement equipment.
