摘要
介绍了差分跳频技术的特点,构造了一类基于回归移位寄存器的频率转移函数。此类频率转移函数具有最大化的自由距,并且具有实现简单,可控参数多的特点。应用马尔科夫链理论对构造的频率转移函数的性能进行了分析。证明了基于回归移位寄存器的频率转移函数产生的频率序列是遍历的马尔科夫链,给出了该链到达平稳状态所需的状态转移步数。
In this paper, the characteristics of the DFH technologies are described, and the frequency transition function based on the recursive shift register is proposed. The proposed frequency transition function is easy for implementation and has a number of controllable parameters. The theory of Markov chain is used to analyze the performance of the proposed frequency transition function. It is proved that the frequency sequence generated by the proposed frequency transition function is an ergodic Markov chain. ...
