| 摘 要： | 研究基于调频差分混沌键控的水印加密方法。该方法使用功率恒定的信号作为栽波，将混沌信号变换成具有混沌相位的恒定功率波形，减小信号提取时的误码率。在不需要建立混沌自同步机制的条件下，利用差分相关技术实现混沌数字通信的方法，采用该技术可以提高编码信息的保密性，同时可以加强编码信息的抗干扰能力。实验表明，将该技术引入到水印方法中，对待嵌入水印进行编码，可以使得信息的内容具有更好的保密性和抗干扰性。

| Abstract: | This paper researches on the watermark encryption method based on the FM-DCSK.A carrier signal of constant power is used.A chaos signal is converted into the wave of constant power with a chaotic phase.The error rate is reduced when extracting.Without the need to establish mechanisms for self-synchronization of chaotic conditions,chaotic digital communications is implemented by the differential related technology,which is used to improve the coding of confidentiality,as well as to strengthen the anti-jammin... |
