Title: Innovations and Achievements of Jin Hong Kim

Introduction

Jin Hong Kim is a prolific inventor based in Lake Zurich, IL, holding a remarkable portfolio of 20 patents. His contributions have significantly impacted the field of digital communications, particularly in the design and implementation of advanced QAM systems.

Latest Patents

One of Jin Hong Kim's latest innovations is a frame structure for a QAM system. This patent introduces a novel framing method for a variable net bit rate digital communications system that employs various QAM constellations and punctured trellis code combinations, each identified as a distinct mode. The innovative frame structure allows for a variable integral number of QAM symbols per frame, contingent upon the selected mode. Importantly, the number of bytes and Reed-Solomon packets per frame remains constant. This is particularly groundbreaking as it accommodates modes where the number of data bits per QAM symbol is fractional. Additionally, the number of trellis coder puncture pattern cycles per frame is consistently an integer across all modes. This thoughtful arrangement enhances the synchronization of critical receiver processing blocks such as the Viterbi decoder, de-randomizer, byte de-interleaver, and Reed-Solomon decoder, simplifying the overall communication process.
