Pseudo random binary sequence 伪随机二元序列
Many researches have been done to create pseudo-random binary sequence which can be a substitute of conventional sequence 但传统序列存在数量少,周期短等缺点,使通信系统性能不尽如人意。
The method encrypts the copyright information into binary sequence for repeated embedding and the intensity of watermarking can be set by the user 即将版权信息加密成二进制序列,重复嵌入文本中,水印嵌入的强度由用户决定。
The function of the assembler is to change assembly language to binary sequence, which makes it easier for the user to program with the chip 汇编器将芯片的汇编语言转换为芯片可以执行的二进制代码,使芯片的应用者不必使用二进制代码进行开发。
From the point of view of a computer scientist, all software consists of a sequence of 1 s and 0 s, and, therefore, all text and text fragments consist of binary sequences 从计算机科学家的角度看,所有软件都是由1和0组成的,因此所有文字和文字段落都是由二进制序列组成的。
