Abstract
Hyperchaos sequences have been widely used as complex pseudorandom sequences. However, the autocorrelation performance of some well known Hyperchaos sequences, such as Hopfield sequence, is poor, and their applications are limited. Based on recently presented APAS theorem, we have modified the Hopfield map to Symmetrical-Hopfield(S-Hopfield) map, and the autocorrelation performance of the S-Hopfield sequence is excellent, whereas other performances of the S-Hopfield sequence remain invariant or become better, and this sequence can be used more widely.
