19 May 2020 | Abstract: | 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). | Source: | arXiv, 2005.9238 | Services: | Forum | Review | PDF | Favorites |
