B2

To suppress deterioration of accuracy of interference elimination targeted on a desired signal and an interference signal between different radio communication systems or different radio communication standards.SOLUTION: A reception device comprises: a sampling part for performing sampling of a reception signal at a frequency that is an integer multiple of the least common multiple of a desired signal sampling frequency and an interference signal sampling frequency; a sampling frequency conversion part for converting a sampling signal to have the interference signal sampling frequency; an interference signal replica generation part for generating a replica signal of an interference signal using the signal after the conversion; a sampling frequency conversion part for converting the replica signal to have a reception signal sampling frequency; a subtraction part for subtracting the replica signal after the conversion from a reception signal sampling signal; a desired signal sampling frequency conversion part for converting a difference signal to have the desired signal sampling frequency; and a desired signal reception part for performing reception processing of a desired signal using the difference signal after the conversion.SELECTED DRAWING: Figure 2
