Title: Hyoung-Nam Kim: Innovator in Feedback Cancellation Technology

Introduction

Hyoung-Nam Kim is a prominent inventor based in Busan, South Korea. He has made significant contributions to the field of telecommunications, particularly in feedback cancellation technology. With a total of 7 patents to his name, Kim's work has advanced the efficiency and effectiveness of radio signal processing.

Latest Patents

Among his latest patents is an "Apparatus and method of feedback cancellation for radio signal." This invention includes a feedback signal cancellation apparatus that utilizes a first RF receiver to down-convert a received RF signal to a predetermined frequency band. It features a subtractor that subtracts a replica of a feedback signal from the down-converted signal, along with a transmission signal generator that creates a repeater output signal using the feedback-cancelled signal. Additionally, a second RF receiver down-converts the RF signal outputted from the RF transmitter, while a reference signal generator produces a reference signal devoid of DC pilot. A replica generator then generates a filter coefficient using correlation between the feedback-cancelled signal and the reference signal, ultimately creating a replica of the feedback signal.

Another notable patent is the "On-channel repeater for feedback capable of removing feedback signals based on pilot partitioning and method thereof." This invention provides an on-channel repeater that efficiently removes feedback signals by quickly adapting to rapidly changing feedback channels. It reduces the filter-coefficient update interval through pilot partitioning, allowing for more frequent filter-coefficient creation. The on-channel repeater consists of a receiver, a subtractor, a replica creator, and a transmitter, all working together to enhance signal clarity.
