Estimation of consistent time delays in subsample via auxiliary-function-based iterative updates

K Yamaoka, Y Wakabayashi, N Ono - arXiv preprint arXiv:2203.09723, 2022 - arxiv.org
In this paper, we propose a new algorithm for the estimation of multiple time delays (TDs).
Since a TD is a fundamental spatial cue for sensor array signal processing techniques …
