To improve the application of audio watermarking technology in mobile Internet and realize the real-time interaction between the radio or television programs and the audience,a cross spread audio watermarking algorithm (CSS) based on spread spectrum audio watermarking (SS) was proposed.The high correlation between the cross frames of the audio signal was used to decrease the variance of the decision statistic and lead to a small error probability.An improved cross spread audio watermarking algorithm (ICSS) was proposed to further improve the robustness of watermarking.Theoretical analysis and ...
