RELAY DEVICE, RELAY SATELLITE, AND SATELLITE COMMUNICATION SYSTEM

摘要

The followings are included: a reception analog switch matrix 22 that outputs, to two or more reception processing units, a wideband reception signal in a band wider than the bandwidth processable by the reception processing unit for each of reception ports 15-1 to 15-N; a connecting unit 31 that outputs demultiplexed signals demultiplexed by the reception processing units to transmission processing units; a transmission analog switch matrix that outputs, to the same transmission antennas, signals subjected to transmission processing by one or more of the transmission processing units to which the demultiplexed signals corresponding to the same reception signals are input; a local generating unit 25 that generates and transmits two or more local signals having different frequencies to the reception processing units; a local-phase-difference calculating unit 41 that calculates a phase difference between the local signals and inputs the phase difference to the reception processing units; and reception-phase correcting units 29-1 to 29-N that perform phase correction on the basis of the phase difference. The reception processing units, when the wideband reception signal is input, apply reception processing to divided signals obtained by extracting a part of bands of input signals on the basis of the local signals.
