Abstract

A method for detecting offset signal corresponding to transmission leakage signal is disclosed, whereby reception sensitivity can be improved by accurately offsetting a leakage signal in transmission signal mixedly inputted into the reception signal in a radio transceiver, and an offset signal corresponding to a transmission leakage signal can be rapidly detected in the radio transceiver to rapidly offset the transmission leakage signal included in a reception signal.

Description

technical field [0001] Teachings consistent with exemplary embodiments of the present invention relate to a method for detecting a bias signal corresponding to a transmit leakage signal, and more particularly to a method for detecting a bias signal corresponding to a transmit leakage signal employed in a radio transceiver system. Signal method. Background technique [0002] In the case of systems like RFID systems using the same transmit and receive frequencies, separation means are required to separate the transmit signal from the receive signal. For example, in RFID systems, readers use circulators or directional couplers to separate the transmitted signal from the received signal. In a general transceiver communication system, one antenna is used and different frequencies are used when transmitting and receiving signals. At this time, part of the transmission signal leaks and mixes with the reception signal. Therefore, in order to separate the transmission of a signal ...
