Implementation of the DSSS method in watermarking digital audio objects
Abstract
The paper presents the results of implementation in the Matlab environment for watermarking
embedder and extractor based on the Direct Sequence Spread Spectrum (DSSS). A block
diagram of watermarking system, an analysis of watermarked signal reproduced as well as
watermarking system robustness to degrading factors: lossy compression, signal-to-noise ratio
(SNR) as well as a change in sampling frequency, were shown.
