In this paper, a variable step size adaptive IIR notch filter is proposed to solve the problems
of estimating and tracking the frequency of sinusoidal signal polluted by broad band noise …

The best adaptive algorithm requires fast convergence speed, low variance, unbias and low
steady-state mean square error (MSE) in both low and high signal-to-noise ratio (SNR) …

Adaptive infinite impulse response (IIR) notch filters are very attractive in terms of their
reasonable performances and low computational requirements. Generally, it is very difficult …

传统的空时自适应处理算法对空间不同于来向的干扰可以有效地抑制, 但对与信号同向的窄带
干扰抑制程度不够, 同时滤除部分有用信号. 对级联IIR 陷波滤波器的自适应算法进行了讨论 …

In this paper, first of all, a simplified variable step-size (VSS) plain gradient (SVSS-PG)
algorithm is proposed for a second-order IIR notch filter with constrained poles and zeros. It …

This paper addresses the problem of accurate estimation and rapid adaptation of abrupt
frequency changes from noisy sinusoidal signals. A two‐filter adaptive algorithm is proposed …

An arctangent (AT) based adaptive algorithm for a first-order complex adaptive IIR notch
filter (CANF) is proposed in this paper. The objective of this work is to overcome some …

This paper deals with a state-space approach for adaptive second-order IIR notch digital
filters with constrained poles and zeros. A simplified iterative algorithm is derived from the …
