Document Type and Number:
WIPO Patent Application WO/2024/005297
Kind Code:
A1
Abstract:
A method carried out by an electronic device, according to the embodiments, may comprise a step for identifying a channel bandwidth. The method may comprise the steps of: on the basis of the channel bandwidth and a quantity of resources allocated in the channel bandwidth, identifying one or more active digital pre-distortion (DPD) units among a plurality of DPD units of a DPD circuit; generating a DPD output signal of the DPD circuit on the basis of the one or more active DPD units; and generating an amplifier output signal on the basis of the DPD output signal of the DPD circuit, a digital-to-analog converter (DAC), and a power amplifier (PA). While the DPD output signal is being generated, 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 may be deactivated.
