摘要
水声信道复杂多变的特点给信息隐藏技术在水下的应用带来了很大的困难,最大的挑战就在于多途效应。通过建立简单的多途效应模型,分析了多途效应引起的误差噪声。讨论了多途效应对信息隐藏算法的影响,并提出了相应的对策。
The underwater channel is complex and changeable,which brings difficulty to the application of steganography underwater,the biggest challenge is multi-path effect.The noise which is caused by multi-path effect is analyzed through the multi-path effect model which is established.The multi-path effect on steganography algorithm is discussed,while the countermeasures are proposed.
