Abstract :
Chaos is a deterministic random process in nonlinear dynamic systems. In this article, we propose a new optimal design method of chaotic spreading sequences with arbitrary period, which optimizes the binary-quantization thresholds with different fractal parameters and initial values. This article simulates and analyzes the design results. The results show that the method can generate a huge amount of high-performance chaotic spreading sequences with arbitrary period.
