An optimal design of infinitely long period spreading sequences based on logistic mapping

摘要

Chaos is more and more used in security communication, because it is a deterministic random process in nonlinear dynamic systems. Chaotic spreading spectrum one application of Chaotic communication. As the basis, this article proposes a new optimal design of infinitely long period chaotic spreading sequences. This method optimizes the binary-quantization thresholds corresponding to different fractal parameters. This article simulates and analyzes the design results, and the results show that the method can generate a huge amount of high-performance and security chaotic spreading sequences.
