Title: The Innovations of Wen-Chang Yeh

Introduction

Wen-Chang Yeh is a notable inventor based in Hsinchu County, Taiwan. He has made significant contributions to the field of technology, particularly in the development of high sensitivity GPS receivers. With a total of 7 patents to his name, Yeh's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is a high sensitivity GPS receiver that includes an acquisition engine and a tracking engine. The acquisition engine processes GPS satellite data at a data rate that is substantially equal to twice the coarse acquisition (CA) code chip rate. This data rate advantageously enables the acquisition engine to process GPS satellite data with relatively less hardware area than traditional GPS acquisition approaches. In one embodiment, the high efficiency acquisition engine may be over-clocked, thereby allowing different phases of a CA code to be correlated quickly. The tracking engine can advantageously process GPS satellite data at a data rate that does not have an integer relationship to the CA code chip rate.
