Abstract: An RF receiver and an RF receiving method are provided using a baseband signal in which a DC offset is removed. In the RF receiver, a noise phase removing unit generates a phase controlled local signal PLOQ in which a phase of a Q signal of a local signal LOQ is controlled, by synthesizing a received RF signal RXIN and the Q signal of the local signal LOQ. A down converter generates a signal in which a DC offset from noise introduced into the received RF signal RXIN is removed, when synthesizing the received RF signal RXIN and the phase controlled local signal PLOQ for frequency-down conversion.

Abstract: An RF receiving apparatus and method which can remove a leakage component in a received signal are provided. In the RF receiving apparatus, a noise removing unit estimates a signal corresponding to a noise component introduced into a received RF signal RXIN by controlling a gain and a phase of a local signal LOI and removes the estimated noise signal from the received RF signal RXIN. An RF signal in which the noise is removed is frequency-down converted in a receiving unit. Also, the noise removing unit utilizes a Q signal of the local signal LOI, LOQ, to control the phase of the local signal LOI.
