提出因果性保持的WaveNet-VNN噪声控制框架,解决深度学习在降噪中的实时性难题。

WaveNet-Volterra Neural Networks for Active Noise Control: A Fully Causal Approach

  • 融合WaveNet与Volterra网络,显式建模非线性并保证实时因果性
  • 在仿真中优于现有深度学习与传统算法,证明先前优势结论有误
  • 适用于高精度实时主动降噪场景,如耳机或工业设备

主动噪声控制(ANC)系统受非线性失真影响,导致传统自适应滤波器性能下降。尽管基于深度学习的ANC方法已出现以应对非线性,但现有方法常忽视关键限制:(1) 端到端深度神经网络模型常违反实时ANC应用中的因果性约束;(2) 多数研究将DNN方法与简化或低阶自适应滤波器比较,而非与充分优化的高阶对应方法对比。本文提出一种保持因果性的时域ANC框架,结合WaveNet与Volterra神经网络(VNNs),明确处理系统非线性的同时确保严格因果操作。与以往DNN方法不同,本方法同时与先进深度学习架构及经过严格优化的高阶自适应滤波器(包括Wiener解)进行对比。仿真结果表明,所提框架在性能上超越现有DNN方法与传统算法,揭示此前宣称的DNN优越性源于与次优传统基线的不完整比较。源代码见https://github.com/Lu-Baihh/WaveNet-VNNs-for-ANC.git。

原文摘要 · Abstract (English)

Active Noise Control (ANC) systems are challenged by nonlinear distortions, which degrade the performance of traditional adaptive filters. While deep learning-based ANC algorithms have emerged to address nonlinearity, existing approaches often overlook critical limitations: (1) end-to-end Deep Neural Network (DNN) models frequently violate causality constraints inherent to real-time ANC applications; (2) many studies compare DNN-based methods against simplified or low-order adaptive filters rather than fully optimized high-order counterparts. In this letter, we propose a causality-preserving time-domain ANC framework that synergizes WaveNet with Volterra Neural Networks (VNNs), explicitly addressing system nonlinearity while ensuring strict causal operation. Unlike prior DNN-based approaches, our method is benchmarked against both state-of-the-art deep learning architectures and rigorously optimized high-order adaptive filters, including Wiener solutions. Simulations demonstrate that the proposed framework achieves superior performance over existing DNN methods and traditional algorithms, revealing that prior claims of DNN superiority stem from incomplete comparisons with suboptimal traditional baselines.
