Abstract
A method of pruning a reference library of signatures and corresponding known structure parameter vectors, each signature composed of a reference signal vector, including, for a given reference signal vector, interpolating a parameter vector and deleting the given reference signal vector and the corresponding parameter vector for a sufficiently small interpolation error. Also a method of accessing an indexed reference library of signatures and corresponding known structure parameter vectors, each signature comprising a reference signal vector, including acquiring an unknown signal, calculating an index vector for the unknown signal; determining error between the index vector for the unknown signal and a calculated reference signal index vector of the library; and thereby identifying as a match candidate for the unknown signal a reference signal vector.
