Autocorrelation performance improvement of CML Hyperchaos sequence based on APAS theorem
Bin Chen · 2011
Hyperchaos sequences have been widely used as a kind of complex pseudorandom sequences. But some well known Hyperchaos sequences, such as CML sequence, have poor autocorrelation performance, and their applications are limited. Based on recently presented APAS theorem, we modified CML map to S-CML map, and S-CML sequence has excellent autocorrelation performance, whereas its other performances are remained invariant or become better, and can be used more widely.
