选择生成器序列概率模型信息论分析

本文运用信息论原理对选择生成器序列进行分析，得到时钟控制序列与钟控输出序列互信息为零的结果，即从选择生成器输出序列中得不到控制序列的任何信息，此外，还得到钟控输入与输出序列互信息的一个下界，所得结论可以为钟控生成器的设计者和分析者提供理论参考．

Information-theoretic Analysis of Probability Model for Alternating Step Generator Sequences

The sequences of Alternating step Generator are analyzed through the method of information theory and obtain some significant results. For example, the mutual information between clock-controlled sequence and clock-controlled output sequence is zero, i.e. one can’t get any information about clock-controlled sequence only from output sequence. Further, the lower bound of mutual information between clock-controlled input and output sequences is given. The results obtained can provide theoretic reference for designer and analyst who study clock-controlled generator.
