Abstract
An electronic device may include: a processor; a power amplifier; a power supply configured to supply power to the power amplifier; a crest factor reduction (CFR) module; and a digital predistortion (DPD) module, wherein the processor is configured to: transmit a first radio frequency (RF) signal, based on a first state of each of the CFR module, the DPD module, and the power supply, in a first transmission interval, the first RF signal being generated from a first baseband signal; identify voltage information of a second RF signal associated with a second transmission interval after the first transmission interval; change a state of each of the CFR module, the DPD module, and the power supply from the first state to a second state, based on the voltage information, in a first reception interval between the first transmission interval and the second transmission interval; and transmit the second RF signal generated from a second baseband signal based on the second state of each of the CFR module, the DPD module, and the power supply, in the second transmission interval.
