Sentence examples for undesired sources from inspiring English sources
The origin of the undesired sources may vary: different speakers, babble, music, traffic noise, TV, etc.
Because of the adaptation criterion exploiting the independence of the sources, a distinction between desired and undesired sources is unnecessary.
In the first stage, the fixed multiobjective optimal beamformer is designed to spatially extract the desired source by suppressing all other undesired sources.
A common approach to remove undesired sound sources is to provide the device with directivity, assuming that the undesired sources and the target source are spatially separated.
For extracting one speech source from the observed signal, an optimum beamformer is desired to suppress all undesired sources whilst preserving the desired one.
The basic idea of designing the optimal FMV is to maintain g(ϕ s, f) = 1 for S f) while minimizing the output signal power (P YY = E[Y f)Y* f)]) of the FMV to suppress other undesired sources.
Fig. 5 Evaluation of the extracted signal quality as a function of the DOA difference between the desired and the undesired source.
Note that even when the desired and the undesired source have equal DOA, the detector provides good accuracy due to the fact that the desired signal is stronger than the interferer at its respective nearest array.
