Latest Patents

Wang-Rae Kim's latest patents include a "Signal transmission apparatus and method" and an "Apparatus and method for compensating pre-distortion of a power amplifier." The signal transmission apparatus comprises a plurality of look-up tables (LUTs) corresponding to operation areas of a nonlinear transmission device, an operational characteristic calculator, a LUT selector, and a predistorter. The LUTs are adapted to store gain values of input signal magnitudes. The LUT selector selects a LUT corresponding to a calculated operational characteristic, generating a gain value output signal. The predistorter then generates a predistorted signal from the gain value output signal and an input signal, which is input to a nonlinear transmission device. The second patent focuses on compensating for pre-distortion of a power amplifier, utilizing a digital pre-distorter controller that generates various compensation coefficients. This innovative approach ensures that the nonlinear characteristics of the power amplifier are accurately checked and that distortion is effectively compensated for.
