摘要

提出了一种无偏约束直接自适应IIR陷波滤波器。该算法采用偏置去除技术去除滤波器参数估计中存在的偏置，从而得到较好的滤波器参数估计。对均值收敛的差分方程进行了封闭的理论分析，并通过计算机仿真得到了验证。

Unbiased constrained adaptive IIR notch filter using direct frequency estimation algorithm

An unbiased constrained direct adaptive IIR notch filter is presented in this paper. The proposed algorithm employs the bias removal technique to remove the bias existing in the estimate of the filter parameter, resulting in good estimate of filter parameter. The theoretical analysis for the difference equation for the convergence in the mean is derived in closed form and confirmed by the computer simulations.
