Claim 8:
9. A method, comprising:
detecting signals and outputting a mixed signal including biomedical signals from a subject and an interference signal;
comparing signal separation results obtained by a plurality of signal separation algorithms including two or more algorithms from a group including a dual signal subspace projection (“DSSP”) method, a temporally extended signal space separation (“tSSS”) method, and principal component analysis (PCA)/independent component analysis (ICA executed on the mixed signal; and
determining a parameter of each of the plurality of signal separation algorithms based on a comparison result, the determining determines the parameter of each of the plurality of signal separation algorithms at which each of the signal separation results is within a predetermined error range as the parameter of each of the plurality of signal separation algorithms.
