Title:
SATELLITE RECEIVER AND SATELLITE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/155952
Kind Code:
A1
Abstract:
This satellite receiver is provided with: N receiving antenna elements; N demultiplexing units; a correlation detection unit which, regarding respective received signals demultiplexed by the N demultiplexing units, calculates a relative phase difference by performing correlation processing on the respective received signals using a receiving antenna element having maximum received power as a reference element, and on the basis of the calculated relative phase difference, calculates an excitation coefficient that cancels out a phase difference between the receiving antenna elements on a subchannel-by-subchannel basis; N phase compensation units which multiply the respective received signals demultiplexed by the N demultiplexing units by the excitation coefficient on a subchannel-by-subchannel basis; and a synthesis unit which synthesizes multiplication results by the N phase compensation units on a subchannel-by-subchannel basis to generate an output signal.
