Title: **Jeongsuk Lee: Innovator in Spectrum-Sensing Technologies**

Introduction

Jeongsuk Lee, an inventive mind based in Kyunggi, South Korea, has made significant contributions to the field of cognitive radios, reflected in his three patents. His innovative spirit and technical expertise have paved the way for advancements in spectrum-sensing algorithms, which are crucial for enhancing the efficiency of wireless communication systems.

Latest Patents

Jeongsuk Lee's latest inventions focus on spectrum-sensing algorithms and methods designed for cognitive radios. These algorithms allow for the reception and analysis of input spectra with multiple channels, facilitating the identification of both occupied and vacant channels through a two-tier scanning process. The coarse scan, conducted at a initial resolution bandwidth, preliminarily determines channels' occupancy, while a fine scan analyzes these channels in greater detail. This dual approach ensures accurate identification of actually occupied and vacant channels.

In another notable patent, Lee developed a long delay generation technique that enhances spectrum-sensing capabilities for cognitive radio systems. This invention includes an Analog-to-Digital Converter (ADC), a memory element (which may utilize shift register banks or Random-Access Memory), and a Digital-to-Analog Converter (DAC). This long delay generator digitizes the received signal, then delays it in the digital realm before reconstructing it as an analog signal, allowing for effective correlation with the original signal to detect meaningful data.
