<P>PROBLEM TO BE SOLVED: To perform compensation of interference without a known signal, and to shorten a processing time about this compensation. Ž<P>SOLUTION: A receiving device having a plurality of signal reception ends includes a self correlation matrix operating means for operating a self correlation matrix of a signal input from the plurality of signal reception ends, a triangular matrix operating means for operating an upper triangular matrix or a lower triangular matrix in which multiplication of the self correlation matrix operated by the self correlation matrix operating means with a complex conjugate matrix becomes the self correlation matrix, a mixture ratio estimating means for estimating a mixture ratio of each input signal into an input terminal after performing linear conversion about the upper triangular matrix or the lower triangular matrix operated by the triangular matrix operating means, and signal separating means for performing separation of signals each input based on the mixture ratio estimated by the mixture ratio estimating means.
