Title:
METHOD AND DEVICE FOR ESTIMATING DIRECTION OF ARRIVAL AND ELECTRONICS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/178802
Kind Code:
A1
Abstract:
The present invention discloses a method and device for estimating direction of arrival and an electronics apparatus. The method comprises: digitalizing input audio signals from a pair of microphones in a microphone array within a certain time frame; buffering the digitalized signals; extracting multiple sub-bands from each of the buffered signals, which covers a predefined bandwidth; calculating phrase shifts in each of the multiple sub-bands for the pair of microphones; performing linear regression according to the phrase shifts and frequencies of the sub-bands, to estimate an estimated relationship coefficient between the phrase shifts and the frequencies of the sub-bands corresponding to the pair of microphones; and calculating the direction of arrival through the estimated relationship coefficient for the pair of microphones.
