Patent attributes
A receiver with adjacent interfering wave elimination function that efficiently eliminates an interfering wave adjacent to a desired reception wave and has few distortion in the receiving signal after detection, is provided with a plurality of bandpass filters for detecting an adjacent interfering wave near a desired reception wave, detects adjacent interfering waves near the desired reception wave, and controls the bandwidths of the bandpass filters that pass the desired reception wave according to the occurrence of the adjacent interfering wave. According to another aspect of the present invention, the bandpass filter for detecting the adjacent interfering wave is made of a digital filter whose center frequency is variable, and the adjacent interfering wave is detected by scanning a frequency region adjacent to the desired reception wave with the digital filter.
