チャネル間線形予測による高分解能時間差推定
Abstract:This document will present the researches I conducted in ATR during my
five months internship. A Direction of Arrival (DOA) Estimator was
studied. To estimate sound source locations or the directions of arrival
(DOA) with precision, a high-resolution time-delay estimator which can
handle fractional sample delay is needed. I then studied an interchannel, linear prediction based time-delay estimator using a microphone
array. The resultant linear prediction filter is an interpolator
estimated by minimizing the inter-channel prediction error squares.
