Chapter six studies characteristics and implementations of pseudo - random sequence generator and data scrambling , and fulfills the de - scrambling function with asic 第六章讨论了伪随机序列和数据扰码的特点,并给出了其asic实现方案。
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 具有优良相关性,大线性复杂度,平衡性,长周期的伪随机序列广泛应用于cdma系统,扩跳频通信系统。
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 以往研究的水印多为伪随机序列,在算法中自动产生一个随机序列将其嵌入,而且检验时只能判断此伪随机序列是否存在。
