Abstract :
In this paper some properties of sequence derived from proposed chaotic dynamic systems, are evaluated and analyzed. First, sequence has been investigated as a sequence with real values. It is followed by evaluating sequence properties when its values have been quantized. It has been demonstrated that these sequences have better performance than gold sequences according to merit factor and W-index criteria.
