| Abstract: | This paper addresses the problem of synchronization in the context of audio data hiding where the goal consists in increasing the information of an audio data set by embedding an imperceptible message. For real time transmissions purposes, audio data hiding have to deal with synchronization issues. This paper proposes an new synchronization scheme that optimizes performances of the systems that are based on spread spectrum synchronization by the use of mathematical morphologic tools. A brief theoretical presentation is made and the enhanced system is derived from the analysis of the advantages and disadvantages. The final scheme allows providing a robust synchronization system and is compared with the classical solutions. | ||
