Keywords: Time Delay Estimation; Accumulated ρ-Cross Power Spectrum with Coherence

Abstract:
Time delay estimation (TDE) remains an important research issue because of its several approaches and large field of digital signal applications. As a solution for this topic, in this paper, we continue the evaluation of the recently proposed accumulated ρ-cross power spectrum with coherence TDE method. The experimental results confirm that the method is faster and more accurate than the previous separated variants. Another key finding is that the TDE based on accumulation of cross-power spectrum is at least twice as accurate as the TDE based on time domain averaging.
