Title: King Y Cheng: Innovator in High-Speed Data Transmission
Introduction
King Y Cheng is a notable inventor based in Tustin, California, with a remarkable portfolio of 10 patents. His work primarily focuses on advancements in telecommunications, particularly in high-speed data transmission technologies. Cheng's innovative contributions have significantly impacted the efficiency of data communication over traditional telephone circuits.
Latest Patents
One of Cheng's latest patents is a high-speed dial-up telephone circuit for full duplex data transmission. This invention describes a 4800 bit-per-second full duplex modem that utilizes the full bandwidth of standard dial-up telephone circuits for simultaneous data transmission in both directions. The design cleverly overlaps two pass-bands in the middle of the telephone band, maximizing bandwidth usage while minimizing error rates caused by remote echoes. Local echoes, which are stronger, are effectively canceled using an echo-canceling technique that operates at the baud rate. Another significant patent involves a timing recovery system for an automatically equalized data modem. This system employs an analog-to-digital converter to sample distorted analog signals, providing a series of distorted digital symbols. An equalizer with variable multiplying coefficients transforms these symbols into undistorted digital signals, with a timing control network adjusting the converter's timing based on variations in the coefficients.
Career Highlights
Throughout his career, King Y Cheng has worked with several prominent companies, including Hycom Incorporated and Anderson Jacobson, Inc. His experience in these organizations has allowed him to refine his skills and contribute to groundbreaking innovations in the field of telecommunications.
