| 摘 要： | 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RLS自适应Volterra滤波器.按照Volterra滤波器的伪线性组合结构,采用RLS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.

| Abstract: | In this paper,the decoupling problem for Volterra adaptive filters is researched, and fully decoupled RLS adaptive Volterra filters is presented. According to the pseudo-linear combination structure of Volterra filters, by applying the principle of RLS filter and constrained optimization theory, a fully decoupled Volterra normal equation with block diagonal input correlation matrix satisfying the minimum cumulative time series error criterion is educed. A fully decoupled RLS adaptive Volterra filter is then designed and a suit of adaptive regulating formulations for the weight vectors of the filter is given out. Simulation results indicate that the proposed method in the paper is efficient. |
