Algorithm and design for pseudo - random sequence ultrasonic spread spectrum distance measurement system 偽隨機碼超聲擴頻測距系統(tǒng)設計與算法
Chapter six studies characteristics and implementations of pseudo - random sequence generator and data scrambling , and fulfills the de - scrambling function with asic 第六章討論了偽隨機序列和數(shù)據(jù)擾碼的特點,并給出了其asic實現(xiàn)方案。
Pseudo - random sequences with optimal properties such as correlation , high linear spans , balance and long period are widely used in cdma system , spread spectrum and hopping communication systems 具有優(yōu)良相關(guān)性,大線性復雜度,平衡性,長周期的偽隨機序列廣泛應用于cdma系統(tǒng),擴跳頻通信系統(tǒng)。
Most of the former watermark techniques usually use pseudo - random sequence as watermark , which produce a sequence randomly in arithmetic for embedding . it only can detect whether the watermark is still remaining or not 以往研究的水印多為偽隨機序列,在算法中自動產(chǎn)生一個隨機序列將其嵌入,而且檢驗時只能判斷此偽隨機序列是否存在。
