时段排列保留了信号的频谱特征,因而可以在与传输原始信号相同的信道下传输已排列的信号。这个特点使得时间分段话音保密系统在战术使用条件下很有吸引力。本文对所谓跳变窗口与滑动窗口的话音保密系统提出排列处理的数学分析。虽然测量战术级的绝对保密性是不可能的,但本文分析了两种处理方式的相对保密性。 The time period preserves the spectral characteristics of the signal so that the arranged signal can be transmitted on the same channel as the original signal was transmitted. This feature makes the time-staged voice privacy system very attractive under tactical conditions. In this paper, the so-called jump window and sliding window voice security system to arrange the mathematical analysis. Although it is impossible to measure the absolute secrecy of the tactical level, this article analyzes the relative confidentiality of the two approaches.
