Title: Garret Shih: Innovator in Communication Systems

Introduction

Garret Shih is a prominent inventor based in Brookline, MA, known for his significant contributions to communication systems. With a total of 12 patents to his name, he has made remarkable advancements in the field of multichannel and wideband communications.

Latest Patents

One of his latest patents is the Automatic Gain Control (AGC) for multichannel/wideband communications system. This AGC system is designed to attenuate an incoming multi-channel signal by providing a gain. It further adjusts each individual channel of the multi-channel signal by supplying a second gain if needed. The system ensures that the received signal power is at an optimal level for analog to digital conversion or any other form of signal processing. Additionally, it enables the elimination of mid-packet gain adjustments. Another notable patent is the method and apparatus to track gain variation in orthogonal frequency division multiplexing (OFDM) systems. This innovation addresses gain variations during a packet, which can lead to significant performance degradation in communications systems that utilize high order quadrature amplitude modulation (QAM). The method and associated apparatus track such variations in an OFDM system, completely eliminating any performance degradation. Gain estimation and compensation are employed using pilot subcarriers in the payload of an OFDM data packet, ensuring accurate gain estimations.
