Introduction

Pei-Jun Shih is a notable inventor based in Tainan County, Taiwan. With a total of six patents to his name, Shih has made significant contributions to the field of signal processing. His latest innovations focus on improving the efficiency and accuracy of channel estimation and symbol boundary detection methods, demonstrating his expertise in advanced communication technologies.

Latest Patents

Shih's most recent patents encompass two groundbreaking inventions. The first is a **Channel Estimation and Symbol Boundary Detection Method**. This method relates to a channel estimation approach used with a received signal containing multiple data bursts transmitted through various path channels. The process begins with the generation of at least one correlation pattern based on decoded preamble symbols. Following this, cross-correlation of the correlation pattern with the received signal produces results that help determine the channel impulse response (CIR) and the symbol boundary.

The second patent is a **Digital Intermediate Frequency (IF) Demodulator**. This invention details a digital IF demodulator designed for processing a digital IF signal converted from a radio frequency (RF) signal. It features multiple components including a numerically controlled oscillator (NCO), a down conversion circuit, a phase-locked loop carrier recovery circuit, and a video baseband demodulator. This system effectively generates composite video signals, enhancing the quality of received data.
