A multi- piecewise Sine chaotic map and its performance analysis

Sine chaotic map is another type of chaotic map, but the map has problems such as small parameter range and uneven sequence distribution. In view of this, this paper proposes a multi-piecewise Sine chaotic map (MPSC) based on the idea of multi-piecewise representation of chaotic map. MPSC uses modular arithmetic, and can make the generated chaotic sequence more uniform by increasing in the number of Piecewise interval and control parameters. The experimental results show that MPSC not only has a larger parameter range, better randomness and initial-value sensitivity, but also increases the range of chaos interval with the increase of the number of segments and control parameters, and the chaos performance is further improved.
