论文摘要
由于可以利用太空域信息，因此通常使用麦克风阵列光束形成，以通过抑制方向性干扰来增强语音的质量。但是，随着麦克风数量的增加，复杂性将增加。在本文中，提出了使用最大信号噪声比（SNR）滤波器的简明束形方案，以降低光束成型的复杂性。最大SNR滤波器是通过使用语音源定位（SSL）的估计排序方向（DOA）和独立向量分析（IVA）的求解方法来实现的。我们的实验表明，与其他广泛使用的算法相比，所提出的算法获得了更高的信噪比和噪声比（SINR）的增益。
Since space-domain information can be utilized, microphone array beamforming is often used to enhance the quality of the speech by suppressing directional disturbance. However, with the increasing number of microphone, the complexity would be increased. In this paper, a concise beamforming scheme using Maximum Signal-to-Noise Ratio (SNR) filter is proposed to reduce the beamforming complexity. The maximum SNR filter is implemented by using the estimated direction-of-arrival (DOA) of the speech source localization (SSL) and the solving method of independent vector analysis (IVA). Our experiments show that when compared with other widely-used algorithms, the proposed algorithm obtain higher gain of signal-to-interference and noise ratio (SINR).
