Abstract :
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.
