METHOD FOR REMOVING FEED BACK SIGNAL IN REPEATER AND REPEATER

摘要

An objective of the present invention is to provide a method for removing a feedback signal in a repeater and a repeater thereof. According to the present invention, provided is a repeater capable of removing a feedback signal, which includes: a first antenna port for receiving a transmission signal transmitted from a terminal; a second antenna port for transmitting the transmission signal to the terminal and receiving a reception signal from the terminal; a first path for transferring the transmission signal from the first antenna port to the second antenna port; a second path for transferring the reception signal from the second antenna port to the first antenna port; and a first coupler connected between ends of the first and second paths to transfer the transmission and reception signals between the first and second antenna ports, wherein, when the transmission signal is transferred through the first coupler to the second antenna port, the first path generates a first offset signal which offsets a first feedback signal reflected by the fist coupler and transferred to the second path.
