Electronic device and method for digital predistortion in wireless communication system

An electronic device, comprising:

• at least one processor comprising processing circuitry;
• a digital pre-distortion (DPD) circuit;
• a digital-to-analog converter (DAC);
• and
• a power amplifier (PA),
• wherein the at least one processor is individually and/or collectively configured to:
• identify a channel bandwidth;
• identify one or more active digital pre-distortion (DPD) units from a plurality of DPD units of the DPD circuit, based on the channel bandwidth and an amount of resources allocated within the channel bandwidth;
• control the DPD circuit to generate a DPD output signal of the DPD circuit based on the one or more active DPD units;
• generate an amplifier output signal, based on the DPD output signal of the DPD circuit, through the DAC, and the PA,
• wherein at least one DPD unit among the plurality of DPD units of the DPD circuit, which is different from the one or more active DPD units, is deactivated while the DPD output signal is generated.
