摘要 |
提出了一种适应于短波窄带信道的自同步音频水印算法.该算法具有如下优点: (1) 在隐藏水印信息的同时 ,嵌入同步信号 ,使得水印具有时钟自同步和数据自同步的能力. (2) 水印信号基于窄带信道的传输 ,适用于短波广播. (3) 水印信号能够抗拒短波传输中的各种干扰.实验表明:该算法能够实际地应用于短波节目的水印嵌入 ,对于短波传输中的各种干扰都有较好的鲁棒性. 关键词 数字水印;音频水印;自同步;短波;窄带 |

This article present s a novel self synchronizing audio watermark algorit hm for short wave nar row band channel . This algorithm has the following merit s : (1) While the watermark information being hideaway , synchronized signal is inserted , which enables the watermark to have the clock selfsynchronizing and the data self2synchronizing abilities. (2) The watermark can be transmit ted through nar row band channel , which is suitable for the shortwave broadcasting.(3) The watermark signal can resist dist urbances during shortwave transmission. The experi ment sindicate that , this algorithm can be applied to watermark insertion for shortwave program ,and it showes satisfactory robust ness for realworld application.Keywords digital watermark ; audio watermark ; selfsynchronizing ; shortwave ; nar rowband |
