本文从维纳滤波角度简述自适应滤波器及自适应噪声消除的基本原理。在微机上实现对实际语音的自适应消噪处理,其结果为进一步研制实用的自适应消噪器打下了基础。
This paper briefly introduces the basic principle of adaptive filter and adaptive noise cancellation from Wiener filtering. On the computer to achieve the actual voice of the adaptive noise reduction, the results for further development of practical adaptive noise reduction laid the foundation.
