Abstract :
This paper deals a novel pseudonoise sequence with imperceptibility in conceptually significant region of human auditory system. The proposed sequence was generated from a typical pseudonoise sequence by the canonical signed digit coding and ordered pair transition. Frequency and auto- and cross-correlation analysis were tested for security, randomness and imperceptibility. The proposed sequence is applicable for audio watermarking with imperceptibility.
