Title: Innovations of James G Hwang

Introduction

James G Hwang is an accomplished inventor based in Vienna, VA, known for his significant contributions to communication systems. He holds two patents that showcase his expertise in pulse position coding technology. His work has implications for airborne, remotely-piloted vehicles, enhancing data transmission capabilities.

Latest Patents

Hwang's latest patents include a "Position Coded Pulse Communication System" and a "Decoding Apparatus and Method for a Position Coded Pulse Communication." Both inventions utilize pulse position coding to transmit multiple channels of data from a ground radar transmitter to a receiver in an airborne, remotely-piloted vehicle. The systems are designed to effectively ignore interfering pulses, particularly those synchronized with the transmitter's pulse repetition frequency (PRF). They incorporate various noise reduction devices, such as redundant transmission of address and channel information, true and complemented data transmission, and tracking of channels in a predetermined order. Additionally, they develop an interference count to recognize synchronous pulses and compare data received for a given channel with subsequent data. The use of windows around expected pulse positions and parity further enhances the reliability of the communication. A novel programming arrangement allows for the storage of several programs in a reduced memory space, making these inventions both innovative and efficient.
