MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091056 A) filed by Samsung Electronics Co. , Ltd. on July 27, 2026, for Electronic Device And Method For Digital Pre-Distortion.
Inventors include Yang, Kwonwoo; Min, Taeyoung; Ku, Jungwoo; Woo, Youngyoon; and Lee, Seonghyeon.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: According to an embodiment, a method performed by an electronic device may comprise a step of obtaining a specified number of samples on the basis of an input signal related to a power amplifier (PA) and an output signal related to the PA. The method may comprise a step of identifying first gain information about the input signal with respect to the output signal. The method may comprise a step of performing, for each of power levels of the output signal, a first process for averaging at least some of gain values within a specified power range among the first gain information. The method may comprise a step of performing, for each of the power levels, a second process for estimating gain values outside the specified power range among the first gain information. The method may comprise a step of changing configuration information about a digital pre-distortion (DPD) circuit of the electronic device on the basis of second gain information about the input signal with respect to the output signal.
