Bo Qin, Heng Zhang, Qiang Fu, Yonghong Yan · 2008
Time delay estimation (TDE) plays an important role in multi-sensor signal processing. Its accuracy and precision are of critical significance. In this paper we propose a robust subsample time delay estimation approach which is based on an improved GCC PHAT algorithm and a sinc-fitted model. Computer simulations clearly demonstrate that this method achieves good results in noisy environments.
