ABSTRACT:
A signal-path delay-estimation method includes correlating a computed coarse delay profile of at least one detected signal path cluster with a waveform to yield a strongest correlated peak for each of the at least one detected signal path cluster. The method also includes, for each of the at least one detected signal path cluster, using the strongest correlated peak to determine an adjusted delay-profile phase, re-sampling the computed coarse delay profile in accordance with the adjusted delay-profile phase, and detecting signal-path-cluster edges using the re-sampled computed coarse delay profile. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly acertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
