Abstract
An interference radio wave elimination device receiving input signals including desired radio frequency signals and interference radio frequency signals that interferences desired radio frequency signal, and then eliminates the interference radio frequency signals. First, an amplifier amplifies the interference radio frequency signal. A digital demodulator (17) demodulates the interference radio frequency signals amplified by the amplifier. A digital modulator (18) modulates the internal carrier signal to make interference radio frequency signals in a digital form by using the demodulated interference information. An adder (21) eliminates the interference radio frequency signals of the digital form from the input signals.
