Abstract: Provided is an electronic device that may include: an antenna; a duplexer configured to separate a Tx signal that the antenna transmits and an Rx signal that the antenna receives; an amplifier configured to amplify an input signal and to transmit the amplified input signal to the duplexer; a memory storing a digital pre-distortion (DPD) table; a transceiver; and a processor configured to: control the transceiver to transmit, to the amplifier, a first signal in a first frequency band corresponding to the Tx signal; determine whether to perform pre-distortion of the first signal, based on a reception performance of the Rx signal in a second frequency band; perform the pre-distortion of the first signal by making reference to the DPD table configured to decrease a strength of the first signal in the second frequency band; and control the transceiver to transmit the pre-distorted first signal to the amplifier.
