摘要： The present invention enable to separate source signals from mixture signals into which the source signals are mixed temporally and spatially, where the number of source signals is more than or equal to the number of mixture signals. A signal storing portion 12 stores the mixture signals input into a signal input portion 11, and a formulation portion 131 in a signal separation portion 13 extracts the mixture signals stored in the signal storing portion 12 and formulates them as an operation expression using a basis matrix composed of plural small matrixes that consist of bases with time symmetry. A learning algorithm application portion 132 applies a learning algorithm based on overcomplete representations, a mixture matrix calculating portion 133 calculates a mixture matrix, a source signal estimating portion 134 estimates source signals separated from the mixture signals, and an output portion 14 outputs the calculated mixture matrix and the estimated source signals.
摘要翻译：本发明能够将源信号与源信号在时间和空间上混合的混合信号分离，其中源信号的数量大于或等于混合信号的数量。信号存储部分12将输入的混合信号存储在信号输入部分11中，信号分离部分13中的配制部分131提取存储在信号存储部分12中的混合信号，并使用基矩阵由具有时间对称性的基底组成的多个小矩阵组成。学习算法应用部分132应用基于过度完整表示的学习算法，混合矩阵计算部分133计算混合矩阵，源信号估计部分134估计从混合信号分离的源信号，并且输出部分14输出所计算的混合物矩阵和估计的源信号。
