Abstract
A signal separating apparatus includes circuitry to separate a signal of interest and other signal other than the signal of interest from each other in accordance with spatial information on a plurality of sensors installed at locations different from each other. The circuitry sets a parameter based on a spread of a subspace of the signal of interest, determines a degree of separation that serves as an index indicative of whether the set parameter is appropriate, and separates the signal of interest and the other signal from each other using the degree of separation.
Claims14
A signal separating apparatus, comprising:
- circuitry configured to separate a signal of interest and another signal, different than the signal of interest, in accordance with spatial information on a plurality of sensors installed at locations different from each other, wherein
- to separate the signal of interest and the other signal, the circuitry is further configured to
- calculate a degree of matching between a first area and a second area, the first area being a region of subspace of the signal of interest and the second area being where the signal of interest is generated;
- set a spatial separation parameter based on the degree of matching;
- determine a degree of separation that serves as an index indicative of whether the set spatial separation parameter is appropriate;
- and
- separate the signal of interest and the other signal from each other using the degree of separation.
A signal separating method, comprising:
- separating a signal of interest and another signal, different than the signal of interest, in accordance with spatial information on a plurality of sensors installed at locations different from each other, the separating including:
- calculating a degree of matching between a first area and a second area, the first area being a region of subspace of the signal of interest and the second area being where the signal of interest is generated;
- setting a spatial separation parameter based on the degree of matching;
- determining a degree of separation that serves as an index indicative of whether the spatial separation parameter set in the setting is appropriate;
- and
- separating the signal of interest and the other signal from each other using the degree of separation.
A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors, cause processors to perform a signal separating method comprising:
- separating a signal of interest and another signal, different than the signal of interest, in accordance with spatial information on a plurality of sensors installed at locations different from each other, the separating including:
- calculating a degree of matching between a first area and a second area, the first area being a region of subspace of the signal of interest and the second area being where the signal of interest is generated;
- setting a spatial separation parameter based on the degree of matching;
- determining a degree of separation that serves as an index indicative of whether the spatial separation parameter set in the setting is appropriate;
- and
- separating the signal of interest and the other signal from each other using the degree of separation.
