| Abstract(in English) | An omnidirectional sound source localization method based on a role selection of microphone pairs has been developed. Since an estimation accuracy of this method is prevented due to a low spatial resolution, GRODMIC having a high spatial resolution is instead applied. In GRODMIC, multiple ripples cause in a group delay characteristics when an excess filter order is applied, and thus the estimation accuracy is degraded. In such a case, it is considered that multiple intersections cause around the desired group delay. Therefore, it is expected that the estimation accuracy can be improved by obtaining samples from excess ripples. In this paper, a method for selecting group delay samples is studied, in which FIR-IIR filter structure is applied. |
