<p>The present invention is provided to configure an RF circuit in which a TDD signal and an FDD signal can be complexly transmitted and received at the same time. In other words, the present invention relates to a system and a method for simultaneously transmitting and receiving TDD/FDD signals, which simultaneously transmit/receive the FDD signal while simultaneously transmitting/receiving the TDD signal. The system for simultaneously transmitting and receiving TDD/FDD signals comprises: an upper node filter bank to be matched with an upper node antenna; a lower node filter bank to be matched with a lower node antenna; a forward amplification unit for transmitting a reception signal to the lower node filter bank by amplifying the reception signal of the upper node filter bank and removing interference of a feedback signal; a backward amplification unit for transmitting a reception signal to the upper node filter bank by amplifying the reception signal of the lower node filter bank and removing interference of a feedback signal; and a control unit for controlling the forward amplification unit and the backward amplification unit.</p> |
