Abstract

An apparatus for resolving an ambiguity from a DOA estimate includes a DOA estimate analyzer for analyzing the DOA estimate to obtain a plurality of ambiguous analysis parameters by using a bias information, the bias information representing a relation between a biased and an unbiased DOA estimate, and an ambiguity resolver for resolving the ambiguity in the plurality of ambiguous analysis parameters to obtain a non-ambiguous resolved parameter.
