摘要
提出一种稳定的IR自适应滤波器,并给出了系数迭代的非线性梯度算法。计算机模拟结果表明:它能够有效抑制JSR很高的单频连续波(CW)干扰及部分频带型窄带干扰,从而使FIR滤波器的固有缺陷得以克服。
This paper puts forwards a stable IIR adaptive filter, along with the nonlinear gradient algorithm concerning its coefficient iteration. Simulation results demonstrate that under high JSR circumstance, the proposed IIR filter can efficiently suppress not only the CW interference but also the partial band NBI.
