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.
Claims15
An apparatus for resolving an ambiguity from a DOA estimate, the apparatus comprising:
- a DOA estimate analyzer for analyzing the DOA estimate to acquire 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 acquire a non-ambiguous resolved parameter.
A method for resolving an ambiguity from a DOA estimate, the method comprising:
- analyzing the DOA estimate to acquire 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
- resolving the ambiguity in the plurality of ambiguous analysis parameters to acquire a non-ambiguous resolved parameter.
A computer program comprising a program code for performing the method for resolving an ambiguity from a DOA estimate, the method comprising:
- analyzing the DOA estimate to acquire 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
- resolving the ambiguity in the plurality of ambiguous analysis parameters to acquire a non-ambiguous resolved parameter,
- when the computer program is executed on a computer.
