Claim:
1. A method comprising: determining, at a fractional delay estimation component of a system, an integer component and a fractional component of a first path delay introduced by a processing path of the system based on a transform of a first vector inserted into the processing path at an input of a section of the processing path and based on a transform of a first feedback vector received from a feedback path of the system and representing the first vector; determining, at the fractional delay estimation component, an integer component and a fractional component of a second path delay in the processing path based on a third transform of a third vector inserted into the processing path at an output of the section of the processing path and based on a fourth transform of a second feedback vector received from the feedback path and representing the second vector; and estimating, at the fractional delay estimation component, a delay introduced by the section of the processing path based on a difference between the first path delay and the second path delay.
