摘要
提出将Logistic混沌序列与m序列以异或方式结合形成一类混合混沌序列的方法。用理论与统计分析相结合的方法对该混合混沌序列的周期、平衡性、相关性及线性复杂度等特性进行了系统分析。分析结果表明：该混合混沌序列的各项特性均较好，产生方法简单，可用数字电路实现，是一类很有应用前景的伪随机序列。
A class of mixed chaotic sequence, which is produced by combining logistic sequence and m sequence in the form of exclusive-OR, is presented in this paper. The period, balance, correlation and linear complexity for a class of mixed chaotic sequences are analyzed systematically. The results show that the properties of the mixed chaotic sequence are good, and the sequence generator can be easily realized by the use of digital circuits. It is a class of promising pseudo-random sequence in practical applications.
