Title: MULTI-BEAM SATELLITE COMMUNICATION SYSTEM, RELAY DEVICE, AND CONTROL DEVICE
Abstract:
In the present invention, a relay-side reception unit (931) receives a relay signal (99), an analog relay unit (932) performs analog processing to output the relay signal (99) the frequency bandwidth of which is controlled, and a digital relay unit (933) performs digital processing to output the relay signal (99) the frequency bandwidth of which is controlled. A relay-side transmission unit (934) transmits the relay signal (99) outputted by the analog relay unit (932) and the digital relay unit (933). A relay-side control unit (935) controls the analog relay unit (932) and the digital relay unit (933) in accordance with an analog relay unit control signal (941A) and a digital relay unit control signal (941D) which indicate the frequency bandwidth of the relay signal (99).
