ABSTRACT:
According to an aspect of the present invention, there is provided with a radio receiver including: one or more antenna which receives radio signals; a plurality of filters which selectively output signals in respective reception bands from the radio signals received by the antenna, adjacent reception bands partially overlapping each other; a plurality of A/D converters disposed correspondingly to the filters to convert the signals output from the respective filters to digital signals; extracting units which extract signal components of a boundary radio signal spreading across at least two reception bands adjacent to each other from digital signals associated with the at least two reception bands adjacent to each other; a combining unit which combines the signal components extracted by the extracting units to restore the boundary radio signal; and a demodulation unit which demodulates the boundary radio signal restored by the combining unit.
