本文認為,色度dc系數是魯棒性非常好的參數,因而選擇色度dc系數作為水印信息載體,同時,採用可變的步長選擇部分系數,保證了水印的隱形性;在嵌入水印時,本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案,由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中,即使某一圖組收到一定破壞,也能夠恢復水印信息,使水印的健壯性得到提高;此外,為了提高水印信息的安全性,在嵌入水印信息時,根據用戶輸入的id號和密碼,利用本文構造的混沌系統產生的混沌序列對水印信息進行變換,同時,對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整,這樣,未授權用戶不能提取水印信息,也難以擦除其中的水印信息,因為嵌入的位置是未知的。Based on the analysis of vhf - rc, the method of applying chaos direct sequence spread spectrum communication ( cds - ssc ) to ahts has been studied and discussed in this thesis. in this method, cds - ssc, which combines chaos sequences ( cs ) of high rand quality with ds - ss excelling in resisting interferences, is used to realize the transmission of hydrologic data

現在使用的擴頻碼有m序列, gold碼和r - s碼等,這些擴頻碼具有良好的隨機性,但普遍存在著復雜度低、保密性差以及同一碼族序列數目少等缺點。混沌信號具有類似噪聲、寬帶連續頻譜的特徵,正符合擴頻通信中對擴頻碼的要求,而且混沌系統對初始值極其敏感,可以通過給混沌系統賦予不同的初始值得到為數眾多、不相關的擴頻序列,這正好滿足碼分多址的要求。本文對利用混沌系統應用於擴頻通信作了一些研究工作,主要包括兩部分:第一部分:探討了擴頻通信的基本理論和混沌的基本特性,說明將混沌系統應用於擴頻通信系統的可行性。分享友人
