Abstract
A signal receiving apparatus receives a radio frequency signal sent by a signal transmitting apparatus, where the radio frequency signal includes a transmit end image component. The signal receiving apparatus generates a receive end image component after performing down-conversion processing on the radio frequency signal. The signal receiving apparatus separately removes the receive end image component and the transmit end image component by performing quadrature modulation compensation twice.
