摘要

本文提出了具有理想噪声整形能力的多通道自适应噪声均衡器(ANE)。窄带ANE可以放大或衰减窄带噪声。ANE系统的输出包含剩余的窄带分量，其幅度可以通过调节均衡器的增益参数进行线性和任意控制。宽带ANE通过设计均衡器的整形滤波器来控制剩余噪声频谱。这些ANE系统扩展到多通道应用。

Multiple-channel adaptive noise equalizers

This paper presents multiple-channel adaptive noise equalizers (ANE) with the desired noise shaping capability. Narrowband ANE can either amplify or attenuate narrowband noise. The output of the ANE system contains residual narrowband components, the amplitudes of which can be linearly and arbitrarily controlled by adjusting the gain parameter of the equalizer. Broadband ANE can control the residual noise spectrum by designing the shaping filter of the equalizer. These ANE systems are extended to multiple-channel applications.
