Using APAS theorem to improve the autocorrelation performance of Chebyshev chaotic sequence.

Chaotic sequences have been widely used as a kind of pseudorandom sequence. But some well known Chaotic sequences, such as Chebyshev sequence, have poor autocorrelation performance, and their applications are limited. Based on recently presented APAS theorem, we have modified Chebyshev map to S-Chebyshev map. S-Chebyshev sequence has excellent autocorrelation performance, whereas its other performances remain invariant or become better, and the sequence can be used more widely‥ [ABSTRACT FROM PUBLISHER]
