| Abstract: | A new method is advanced for generating binary chaotic sequences by means of integer arithmetic. We analyzed the correlation property of digital chaotic sequence by logistic maps and compared it with the simulative chaotic sequence. From the statistics,we got its approximate formula and found find that the length of sequences has a very important influence on the correlation property . Finally, the simulation results are presented . |
