The development of a watermarking system that is robust against de-synchronization attacks (DAs) is a major challenge. In this paper we make two steps towards the development of such a system by: i) proposing a fast algorithm for exhaustive watermark detection in the presence of C-LPCD DAs; ii) introducing a new watermarking system that by pre-distorting the watermark to be embedded greatly improves the performance of the exhaustive watermark detector. The validity of the proposed system is tested by means of Monte Carlo simulation on Gaussian white sequences. The results we obtained are rather promising thus suggesting to apply the newly proposed system to the watermarking of real audio sequences.
