摘要

为了解决传统子带自适应滤波算法在处理具有脉冲噪声的 EIV 模型时性能下降的问题,本文提出了基于 M 估计函数的鲁棒总最小均值归一化子带滤波器(TLMM-NSAF)自适应算法。此外,我们还对 TLMM-NSAF 算法进行了详细的理论性能分析,从而确定了算法的稳定步长范围和理论稳态均方偏差。为了进一步提高算法性能,我们提出了一种新的可变步长方法。最后,我们将该算法与其他竞争算法在系统识别和声学回声消除应用中进行了比较。仿真结果证明了我们提出的算法的优越性,以及理论值与仿真值之间的一致性。

Robust Total Least Mean M-Estimate Normalized Subband Filter Adaptive Algorithm Under EIV Model in Impulsive Noise

In order to solve the problem of deteriorating performance of the conventional subband adaptive filtering algorithm when processing the EIV model with impulsive noise, this paper proposes the robust Total Least Mean M-Estimate normalized subband filter (TLMM-NSAF) adaptive algorithm based on the M-estimation function. In addition, we conduct a detailed theoretical performance analysis of the TLMM-NSAF algorithm, which allows us to determine the stable step size range and theoretical steady-state mean squared deviation of the algorithm. To further improve the algorithm's performance, we propose a new variable step size method. Finally, we compared the algorithm with other competition algorithms in applications of system identification and acoustic echo cancellation. Simulation results have demonstrated the superiority of our proposed algorithm, as well as the consistency between the theoretical values and the simulated values.

期刊介绍: Rapid developments in the analog and digital processing of signals for communication, control, and computer systems have made the theory of electrical circuits and signal processing a burgeoning area of research and design. The aim of Circuits, Systems, and Signal Processing (CSSP) is to help meet the needs of outlets for significant research papers and state-of-the-art review articles in the area. The scope of the journal is broad, ranging from mathematical foundations to practical engineering design. It encompasses, but is not limited to, such topics as linear and nonlinear networks, distributed circuits and systems, multi-dimensional signals and systems, analog filters and signal processing, digital filters and signal processing, statistical signal processing, multimedia, computer aided design, graph theory, neural systems, communication circuits and systems, and VLSI signal processing. The Editorial Board is international, and papers are welcome from throughout the world. The journal is devoted primarily to research papers, but survey, expository, and tutorial papers are also published. Circuits, Systems, and Signal Processing (CSSP) is published twelve times annually.
