Abstract
A receiver includes a first and a second amplification unit for amplifying a first and second received signals received by antenna units; a level variation detection unit for performing gain control of the first amplification unit; a maximum received signal level extraction unit for performing gain control of the second amplification unit; and a first and a second frequency conversion unit. The receiver further includes an interference frequency detection unit for detecting a frequency of interference in the second received signal; an interference frequency cut-off unit for cutting off the frequency of the interference; demodulation units for demodulating the respective received signals; noise amplitude calculation unit for calculating noise amplitudes from the respective received signals; equalizing units for correcting amplitudes and phases of the respective received signals; and a combining unit for combining demodulation results from the respective received signals on the basis of noise amplitude detection results.
