Title: Chyi H Lu: Patents in Signal Processing and GPS Technology.

Introduction

Chyi H Lu is an inventor based in Plano, Texas. His patent work includes signal-processing methods and GPS technology. He holds 3 patents.

Latest Patents

One of Lu’s latest patents, “Coherent Synchronization and Processing of Pulse Groups,” describes a method for synchronizing pulse groups without a separate synchronization signal. It selects coherent processing intervals from a data stream, samples the data at defined positions within pulse repetition intervals, and converts the samples into frequency-domain data. The method compensates for phase rotation and applies a fast Fourier transform (FFT) to selected data for display.

Another patent, “Method and System for a Multi Channel and Search Global Position System,” describes a GPS digital signal processor integrated onto a single chip. Its channels process L1 or L2 P(Y) and C/A-code signals, while a search processor supports rapid signal acquisition. The design also includes low-power circuitry, a digital oscillator, a null detector, and eight correlators.

Career Highlights

Lu’s professional experience includes work at Texas Instruments Corporation and Raytheon TI Systems, Inc. His patent portfolio reflects contributions to digital signal processing and satellite-navigation systems.
