RF receiving apparatus and method using DC offset free baseband signal |
摘要 |
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.
