摘要
基于混沌动力系统相空间延迟坐标的重构、混沌序列产生的确定性和非线性机制、混沌序列高阶奇异谱的特征及二阶Volterra自适应滤波模型,提出了高阶非线性HONFIR滤波模型和Sigmoid函数的少参数非线性自适应滤波预测模型,并介绍了相应的自适应算法.
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.
