SIGNAL RECEIVER/TRANSMITTER AND CONTROL MECTHOD THEREOF

摘要

A signal transmitting/receiving device and a control method thereof are provided to efficiently improve signal to noise ratio by performing a DC offset detection/correction and a carrier wave leakage in applying a power source. A transmitting part(200) corrects a receiving signal about a carrier wave leakage, and modulates the corrected signal. A receiving part(400) demodulates a signal received from the transmitting part, and performs a DC offset correction about the demodulated signal. A base-band processing part(100) controls a connection setting between the transmitting part and the receiving part. The base-band processing part detects a DC offset about the signal received from the receiving part. The base-band processing part controls a DC offset correction of the receiving part and a carrier wave leakage correction of the transmitting part based on information about the detected DC offset.
