摘要

我们提出了一种新的复杂自适应IIR陷波滤波器结构，它可用于抑制QPSK通信系统中宽带信号的窄带干扰。该结构基于梯度算法。给出了收敛性的性能分析。结果表明，该算法的收敛速度不受输入白噪声方差的影响。分析了彩色高斯噪声对收敛速度的影响。计算机仿真结果证实了理论预测。

Performance analysis of complex adaptive IIR notch filters

We present a new structure for complex adaptive IIR notch filters which is useful for the rejection of narrowband interference from broadband signals in QPSK communications systems. The proposed structure is based on a gradient algorithm. A performance analysis for convergence properties is developed. It is shown that the convergence speed does not depend on the variance of input white noise. The effects of colored Gaussian noise on convergence speed are analyzed. The results of computer simulation are shown which confirm the theoretical prediction.
