Multistage Volterra Filters for Nonlinear System Modeling

提出多级Volterra滤波器非线性建模方法 ,该滤波器等价于文献 [1]给出的分块解耦Volterra滤波器 ,此方法简化了文献 [1]中复杂的推导过程 .通过比较两种滤波器的均方误差 ,进一步分析其与标准Volterra滤波器的性能差异 ,给出刻画该性能差异的误差量 .

Multistage Volterra filters for nonlinear system modeling are proposed and shown to be equivalent to the partially decoupled Volterra filters as developed in [1]. The approach greatly simplifies the analysis and derivation given in [1]. Furthermore, we analyze the performance of the multistage or partially decoupled Volterra filters by comparison with standard ones.
