摘要：

Recent papers have demonstrated that synchronization in the Lorenz system is highly robust to additive perturbation of the drive signal. This property has led to a concept known as chaotic signal masking and recovery. This paper presents experiments and an approximate analytical model that quantify and explain the observed. robustness of synchronization in the Lorenz system. In particular, explain why speech and other narrow band perturbations can be recovered faithfully, ever! though the synchronization error is comparable power to the message itself.
