发明名称 RADIO RECEPTION DEVICE FOR VEHICLE AND NOISE CANCELLATION METHOD
摘要 A radio reception device for vehicle 100 (200) includes a variable phase shifter 22, an amplitude regulator 23, and an adder 24, and has an arrangement in which a signal of an RF, IF, or baseband stage of a radio receiver mixed with a noise is added to a phase-inverted component of the noise to remove only the noise. Therefore, sound distortion due to loss of sound information does not occur so that a quality sound can be provided.
