ZERO INTERMEDIATE FREQUENCY CORRECTION METHOD, DEVICE AND EQUIPMENT

摘要

The present invention discloses a signal receiving apparatus. The 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. Therefore, signal quality is improved, and complexity of hardware design is reduced.
