摘要:
A high frequency receiver cancels a plurality of noise signals which are contained in a high frequency signal and outputted from a plurality of noise signal sources. The high frequency receiver cancels the noise signals using a plurality of pick-up noise signals extracted from a plurality of pick-up antennas disposed near the noise signal sources. At least one of the pick-up noise signals is selected in descending order of their effects on the degradation of reception quality, thereby completing noise cancelling in a short time.
