摘要
电子对抗技术的发展对军事通信提出了很大挑战。数字水印作为信息隐藏的一个重要分支,为隐蔽通信提供了一条思路。本文采用基于提升方案的小波变换,提高了水印检测的运算速度,采用通用DSP(数字信号处理器)能够实现对水印的实时提取。仿真实验的结果证明音频信号中嵌入水印可以满足军事通信中鲁棒性、实时性和隐蔽性的要求。
The development of electronic countermeasure technology is a challenge to military communication, which calls for better robustness, real-time detection and covertness. Digital watermarking is taken as a branch of information hidden and it offers a mind to covert communication. Lifting wavelet transform increases the speed of extraction in order to meet the demand for real-time extraction. The general DSP（Digital Signal Processor） could accomplish the real-time watermarking extraction. The experiment proves that watermarking embedded into audio could meet the demand of military communication.
