Abstract: 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.
