Title: Keun Hong Chae: Innovator in Spectrum Sensing Technology

Introduction

Keun Hong Chae is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of spectrum sensing technology, holding a total of 9 patents. His work focuses on developing advanced methods and apparatuses for signal processing and navigation systems.

Latest Patents

Among his latest patents is a spectrum sensing apparatus that includes a receiver for capturing analog signals within a specific frequency band. This apparatus features an Analog Digital Converter (ADC) that samples the analog signal to produce a digital output. A correlator then performs auto-correlation on the digital signal, generating a correlation function. The controller interprets this function to determine frequency band occupancy based on the generated image pattern. Another notable patent involves a method for generating an unambiguous correlation function for CBOC (6,1,1/11) signals. This method includes creating delayed signals and performing various autocorrelation operations to derive a main correlation function essential for satellite navigation systems.
