Title: Innovations of Kwang-Eun Ahn
Introduction
Kwang-Eun Ahn is a notable inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of signal transmission technology. With a total of three patents to his name, Ahn's work focuses on enhancing the efficiency and performance of nonlinear transmission devices.
Latest Patents
One of his latest patents is a signal transmission apparatus and method. This invention includes a plurality of look-up tables (LUTs) that correspond to the operation areas of a nonlinear transmission device. The apparatus features an operational characteristic calculator, a LUT selector, and a predistorter. The LUTs are designed to store gain values of input signal magnitudes. The LUT selector identifies a LUT that corresponds to a calculated operational characteristic, generating a gain value output signal. The predistorter then creates a predistorted signal from this output signal and the input signal, which is subsequently fed into a nonlinear transmission device.
Another significant patent by Ahn is the predistortion linearizer and method thereof. This invention incorporates a digital signal processor (DSP) that models the nonlinear characteristics of a high power amplifier (HPA) in real time. It also includes a distortion signal generator that produces a distortion signal based on the DSP's modeling. The main path unit combines the output signal of the HPA with the distortion signal, allowing for the transmission of an input signal without distortion components. This real-time modeling improves the nonlinear characteristics of the power amplifier, maximizing its efficiency.
