Abstract
A method of and system for estimating a parameter of a local maxima or minima of a function. An interpolated local maxima or minima is determined. An interpolation offset is then derived, comprising a deviation between locations of the interpolated and sampled local maxima or minima of the function. An estimate of the parameter is derived from the interpolation offset.

A method of estimating a parameter of a local maxima or minima of a function comprising:
- performing interpolation on samples of the function at or near a local maxima or minima, resulting in an interpolated local maxima or minima;
- deriving an interpolation offset comprising a deviation between locations of the interpolated local maxima or minima and a sampled local maxima or minima;
- and
- deriving an estimate of the parameter from the interpolation offset.
A memory tangibly embodying a sequence of software instructions for performing a method of estimating a parameter of a local maxima or minima of a function comprising:
- performing interpolation on samples of the function at or near a local maxima or minima, resulting in an interpolated local maxima or minima;
- deriving an interpolation offset comprising a deviation between locations of the interpolated local maxima or minima and a sampled local maxima or minima;
- and
- deriving an estimate of the parameter from the interpolation offset.
An apparatus for estimating a parameter of a local maxima or minima of a function comprising:
- means for performing interpolation on samples of the function at or near a local maxima or minima, resulting in an interpolated local maxima or minima;
- means for deriving an interpolation offset comprising a deviation between locations of the interpolated local maxima or minima and a sampled local maxima or minima;
- and
