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.
