Title: Innovations of Seung Won Kim

Introduction

Seung Won Kim is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of telecommunications, particularly in the area of digital broadcasting and equalization techniques. With a total of 3 patents, his work has had a substantial impact on improving signal processing and reception capabilities.

Latest Patents

One of his latest patents is titled "Method and apparatus for blind decision feedback equalization." This invention relates to blind decision feedback equalization, where it selects either a filter signal or a quantized signal as the input for a feedback filter in the decision feedback equalizer (DFE). The invention includes a main filtering unit, a SAG flag determining unit, and a blind feedback controlling unit. It effectively prevents performance degradation caused by error propagation, enhances convergence performance in equalization apparatus, and reduces the symbol error rate (SER) at a steady state after convergence. This technology is particularly useful for receivers in digital television, which require blind equalization.

Another significant patent is "Digital broadcasting service receiver for improving reception ability by switched beam-forming." This invention describes a receiver designed to enhance the reception ability of digital broadcasting services through switched beam-forming. It comprises an array antenna with multiple elements for receiving signals, a demodulation unit for processing these signals, a beam-forming unit for generating beam-forming signals, and a beam selection unit for selectively receiving signals from desired directions. This innovation effectively mitigates multipath interference by utilizing space filtering through beam-forming methods, thereby improving the performance of digital television broadcasting with vestigial sideband (VSB) modulation.
