New Considerations for Accumulated ρ-Cross Power Spectrum Phase with Coherence Time Delay Estimation

Time delay estimation (TDE) has many applications in a variety of digital signal applications. The main issues today are more or less application-dependent, because every specific utilization scenario has its own demands (related to accuracy, computational load, etc.) 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 two times more accurate as the TDE based on time domain averaging.
