According to the advantages of chaotic analog sequences and chaotic binary sequences, this paper proposes a method of generating chaotic binary spread-spectrum sequences by multilevel quantifying. The performance of DS/CDMA communication system is closely related to the mean-square cross-correlation value between sequences, so the distribution of the correlation and the mean-square correlation between the sequences is presented. The theoretical analysis and the results of simulation show that the spread-spectrum sequences generated by the method have good correlation properties, and their quantity is very large.
