1. An electronic device comprising:
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, by providing a first supply voltage to the power amplifier based on a first state of each of the CFR module, the DPD module, and the power supply, in a first transmission interval of a time division duplex (TDD) scheme, the first RF signal being generated from a first baseband signal;
identify voltage information of a second RF signal to be transmitted in a second transmission interval of the TDD scheme after the first transmission interval of the TDD scheme;
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 of the TDD scheme between the first transmission interval of the TDD scheme and the second transmission interval of the TDD scheme; and
transmit the second RF signal generated from a second baseband signal by providing a second supply voltage to the power amplifier based on the second state of each of the CFR module, the DPD module, and the power supply, in the second transmission interval.
