Latest Patents

One of his latest patents is titled "Apparatus and method for reducing peak to average ratio in wireless communication system." The purpose of this invention is to reduce the Peak-to-Average Ratio (PAR) of a transmission signal. A transmission device includes a generation part for generating a cancellation pulse corresponding to a peak component of a transmission signal, and a cancellation part for attenuating the peak component using the cancellation pulse. This invention also includes various embodiments beyond the primary design.

Another notable patent is "Apparatus and method for digital pre-distortion in wireless communication system." This invention provides a Digital Pre-Distortion (DPD) apparatus and method for processing a signal that is input to a power amplifier in a wireless communication system. The DPD apparatus includes a DPD unit configured to pre-distort an input signal that is input to the power amplifier, using DPD information. Additionally, a signal processor captures signals for estimation of the DPD information from each of an input terminal and an output terminal of the power amplifier, detects peak signals of the captured signals, separates the detected peak signals into a plurality of intervals depending on a power level, separately stores the detected peak signals, estimates the DPD information using the peak signals stored for each interval, and provides the estimated DPD information to the DPD unit.
