摘要
本文利用 APD混沌同步控制技术 ,实现了对语音信号的双重保密 ,并通过计算机模拟了信号加密解密的全过程 .本文还讨论了加密信号在传输过程中受到干扰时 ,对解密信号的质量产生的影响 ,同时提供了相应的抗干扰措施 .该语音保密方法简单实用 ,安全可靠 。
This article shows that the two ply secrecy of phonetic is obtained by using the technology of Active Passive Dimension chaos synchronous control and gives how to stimulate the whole process of encoding and decoding. Furthermore,the influence on the quality of the decoded signal when the encoded signal is jammed in transmission is discussed and the corresponding measure of anti jamming is provided. This method of phonetic secrecy is simple,practicable,safe and reliable, and then has a better prospects of application.
