本文研究了Volterra自适应滤波器解耦问题,提出了一种全解耦的RIS自适应Volterra滤波器.按照Volterra滤波器的伪线性组合结构,采用RIS滤波原理和约束优化理论,导出了满足最小累计平方误差指标的具有分块对角形输入相关矩阵的全解耦Volterra标准方程,据此设计了一种全解耦的RLS自适应Volterra滤波器,给出了滤波器权向量自适应修正的一套公式.仿真结果验证了本文方法的有效性.
This paper studies the decoupling problem of Volterra adaptive filter and proposes a fully decoupled RIS adaptive Volterra filter.According to the pseudo-linear combination of Volterra filters, using RIS filter theory and constraint optimization theory, A fully decoupled RLS adaptive Volterra filter is proposed based on the fully decoupled Volterra standard equation with block square and diagonal input correlation matrix with cumulative square error index. Set of formulas. Simulation results verify the effectiveness of the proposed method.
