By assuming that the sound field is an element of this reproducing kernel Hilbert space, we estimate the arrival power based on microphone array signals at only two time points and propose a direction-of-arrival estimation method. One of the features of the proposed method is that the combining process of the frequency bin results is replaced by integration, so that the computational complexity does not change when the frequency range is changed. In addition, the spatial dimension and element placement are arbitrary and the method can be applied to multiple sound sources because it is based on the arrival power estimation. The results of numerical experiments indicate that the higher frequency the better the performance below the aliasing frequency determined by the element placement.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2022-SLP-140"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":216603,"updated":"2025-01-19T15:47:49.240279+00:00","links":{},"created":"2025-01-19T01:17:07.664911+00:00"}
