METHOD AND APPARATUS FOR CORRELATING TWO DATA SECTIONS
摘要
Watermarking of audio signals intends to manipulate the au- dio signal in a way that the changes in the audio content cannot be recognised by the human auditory system. The watermark data are decoded from the received watermarked audio signal by correlation with corresponding candidate reference sequences. One or more of the sync symbols (S1, S2, S3) are embedded twice in the watermark data frame in the encoder. Thereafter a circular correlation is calculated instead of a standard correlation.
