<P>PROBLEM TO BE SOLVED: To provide a wireless apparatus capable of suppressing disturbance on reception of a received radio wave even when a frequency of a transmission radio wave transmitted from a wireless transmission section is close to a frequency of the received radio wave received by a wireless reception section. <P>SOLUTION: A phase amplitude adjustment section 105 receives a transmission signal or its part transmitted from an antenna 101 of a transmission section 102, adjusts the phase and the amplitude of the signal, and produces a signal the phase of which is nearly inverted to the phase of a disturbance wave included in a signal of a reception system and caused by the transmission signal and the amplitude of which is almost equal to the amplitude of the disturbance signal. An adder section 106 adds this signal to a signal resulting from mixing the disturbance wave to the received signal to attenuate the disturbance wave. <P>COPYRIGHT: (C)2007,JPO&INPIT |
