A block shuffle method based on Arnold Transformation, which is traditionally used in Digital Watermark, is put forward for the preprocessing of error concealment. Experiment results show that it can improve the performance of error concealment algorithm.

• 针对传统错误隐藏算法对抗无线信道突发错误的局限性,将原本用于数字水印技术的Arnold 变换作为错误隐藏预处理算法,实验结果表明这种方法能有效提高错误隐藏算法对抗突发错误的性能。
