System implementation of robust time difference of arrival estimation

We combine sound activity detection, sound enhancement, and direction of arrival (DOA) estimation system to an integrated system. We use sound activity detection for finding frames which are sound-dominated, then pass the signal to the subspace based sound enhancement for denoising. Finally, the den...

Summary:We combine sound activity detection, sound enhancement, and direction of arrival (DOA) estimation system to an integrated system. We use sound activity detection for finding frames which are sound-dominated, then pass the signal to the subspace based sound enhancement for denoising. Finally, the denoised signal will be input to DOA detection system for sound tracking. The generalized cross-correlation and phase transformation (GCC-PHAT) based time difference of arrival (TDOA) estimation can detect the TDOA of the sound signal and then calculate the respondent DOA.
