Apparatus and method for signal compensation in wireless communication system

Abstract

The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long-term evolution (LTE). A method performed by a base station in a wireless communication system is provided. The method includes acquiring, by the base station, a first output signal of digital predistortion (DPD), identifying, by the base station, a distortion section from the starting point of a downlink section after an uplink section has ended in a time division duplex (TDD) configuration, identifying, by the base station, compensation information for a power amplifier of a base station in the distortion section, and providing, by the base station, a signal in which the compensation information is applied to a second output signal of the DPD to the power amplifier.

Dependencies are inferred from the claim text.
