提出一种基于Turbo码的数字水印方案。该算法既对水印图像进行编码,又对载体图像进行编码。编码数据在经过较低信噪比的信道传输后,由解码算法能同时恢复水印和载体图像。不同于传统数字水印方法,本文方案要求接收用户掌握Turbo解码密钥,方能正确恢复水印和载体图像。本文给出了方案设计流图,然后给出仿真实验结果,仿真结果表明算法在通信中保护水印和载体图像方面是可行的。

The more numbers of iteration of iterative decoding of Turbo decoding,the more improvement of errors decoding performance.But there is a limitation on the number of iteration of SOVA decoding.Beyond this limitation,the improvement extent can be limitted,and calculation amount and the decoding delay can be increased.In order to decrease unnecesary calculation amount and decoding delay,more efficient stopping criterion of iterative decoding are required.Son an efficient stopping criterion for SOVA decoding is proposed,whose performance is compared and analyzed through simulation.

Turbo解码的迭代解码的循环次数越多,误码性能就越能得到改善。但是SOVA解码的循环次数有一个限度,超过这一限度,改善程度有限,只会增加计算量和解码迟滞。为了减少不必要的计算量和解码迟滞,需要更有效率的迭代解码中止判据。提出为了SOVA(Soft output Viterbi algorithm)解码的高效率的迭代解码中止判据,通过模拟,比较、分析了其性能。
