Improving autocorrelation performance of Skew Tent sequence based on APAS theorem

Chaotic sequences, as a kind of pseudorandom sequences, have been widely used. But some well known chaotic sequences, such as Skew Tent sequence, have poor autocorrelation performance, and their applications are limited. Based on recently presented APAS theorem, we modified Skew Tent map to S-Skew Tent map, and S-Skew Tent sequence has excellent autocorrelation performance and simple structure, whereas its other performances are remained invariant or become better, and can be used more widely.
