Title:
INTERFERENCE WAVE SUPPRESSION DEVICE, RELAY DEVICE, RELAY SYSTEM, AND INTERFERENCE WAVE SUPPRESSION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/105505
Kind Code:
A1
Abstract:
An interference wave suppression device is provided with a digital branching unit (7) for branching a reception signal into branched signals having predetermined bandwidths, an interference wave detection unit (8) for judging whether or not any interference waves exist on the basis of an electricity value with respect to each branched signal, an interference wave suppression unit (9) which outputs a signal value of the branched signal which has been judged to have an interference wave by changing the value to a predetermined value or lower, or outputs the branched signal which has been judged to have no interference waves, and a digital multiplex unit (13) for multiplexing signals output from the interference wave suppression unit (9).
