摘要
提出了一种新颖的基于QAM调制的信息隐藏算法,将隐秘信息作为信道中的噪声嵌入到数字通信系统的I,Q信号中发送;算法进行了实验仿真和性能分析。仿真结果表明基于调制的信息隐藏技术具有较好的不可检测性和较高的安全性。
A novelty information hiding algorithm based on QAM modulation is presented. Based on this algorithm,the secret information could be embeded into the I-Q signal of digital communication system as the channel noise before transmitted . The algorithm is simulated and analysed . The result of simulation shows that the information hiding algorithm based on QAM modulation has good imperceptibility and high security.
