Study on the Calculation Models for Nonlinear Filtering in Chaotic Time-Sequence

Based on the reconstruction of delayed coordination for chaotic-dynamic systems in phase-space, the definiteness and nonlinear mechanism of the production of chaotic sequence, the feature of high-order strangeness spectrum in chaotic sequence and the model of the second-order volterra's self-adaptation filtering, this paper proposes the two models including the high-order nonlinear HONFIR filtering and the calculation of the Sigmoid function's minority parameter, nonlinear, and self-adaptation filtering, and introduces the calculations of self-adaptation.
