摘要 传声器阵列在语音增强中得到了普遍应用。通常时域或频域的维纳滤波方法是作为一种后处理方法在阵列波束形成之后单独使用。从空间滤波的思路出发分析并介绍了传声器阵列的空间维纳滤波的方法,并通过实验证明了空间滤波语音增强方法同时具备了MVDR波束形成及频域维纳滤波的优点。 Microphone array system has been widely used in the application of speech enhancement, and in order to further suppress the noise, the Wiener filtering technique is used to be a standalone post-filtering method after a beam-former. In this paper, the Wiener spatial filtering technique applied to microphone array system is discussed from the view of spatial filtering, and clarified that it integrates the advantages of the MVDR beamformer and Wiener filtering in frequency domain.
