Abstract
A satellite receiver includes: N reception antenna elements; N demultiplexing units; a correlation detection unit configured to perform correlation processing on each of reception signals demultiplexed by the N demultiplexing units with a reception antenna element that receives the highest power being set as a reference element so as to calculate a relative phase difference, and calculate an excitation coefficient for cancelling a phase difference between the N reception antenna elements for each of sub-channels based on the calculated relative phase difference; N phase compensation units configured to multiply the reception signals demultiplexed by the N demultiplexing units, respectively, by the excitation coefficient for each of the sub-channels; and a combiner configured to combine multiplication results from the N phase compensation units for each of the sub-channels to generate output signals.
