Time-delay estimation using Farrow-based fractional-delay FIR filters: Filter approximation vs. estimation errors
Mattias Olsson, Håkan Johansson, Per Löwenborg · 2006
This paper provides error analysis regarding filter approximation errors versus estimation errors when utilizing Farrowbased fractional-delay filters for time-delay estimation. Further, a new technique is introduced which works on batches of samples and utilizes the Newton-Raphson technique for finding the minimum of the corresponding cost function. 1.
