Open publisher page 0 citations

Abstract

Establishes the mathematical expression of statistical properties of chaotic sequences generated by Logistic_Map and analyses its mathematical properties,points out that the statistical properties are identical with those of white noise, and they can suitably be used as spread spectrum sequences in CDMA; and only because of the random intersection, the balance property of this sequence is not so good,presents mH sequence, a novel complex chaotic spread spectrum sequence,to solve this problem, and concludes from experimental results that the mH sequence followed by a intertexture was a good balance property,and the complex chaotic spread spectrum sequence has good properties and excellent anti_decipher ability.
