RF receiving apparatus and method for removing leakage component of received signal

摘要

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.
