| 摘 要： | 本文讨论了用多个低阶的自适应陷波滤波器串联或并联起来过滤多个频率的信号。提出了一种新的代价函数,推导了基于新的代价准则的递归的最大似然估计算法的自适应滤波器,并在模拟实验中验证了该方法对于控制参数收敛的频域范围的效果.

| Abstract: | The parallel and series Adaptive Notch Filter(ANF)can be used to filter several frequencies of Signals.A new cost function is proposed and based on this cost function criterion,recursive maximum likelihood algorithm of ANF is deduced.By using this method,we achieve good results of controling the parame- ter convergence in the limited frequency domain. |
