Abstract :
The base problem in the watermark decoding process using coherent spectrum averaging method is output phase drift. The phase drift or jitter is undesired phenomenon in the output signal in the receiver´s side of watermarking system. This phase drift is a result various stability of the quartz oscillators in the transmitter and receiver A/D converters. The laboratory results presented in this paper shown high efficiency in phase correction during coherent spectrum averaging of the received signal using the drift scanner method.
