Open publisher page 0 citations

Abstract

A commonly used method of calculating TDOA and FDOA is the CAF(cross ambiguity function) in joint estimation of time delay and frequency offset.Narrowband model and wideband model are calculation models of the CAF.Both of them have different algorithm and estimation performance respectively.In this paper,different algorithms and their application conditions and performance of two models are described and analyzed.
