Title: Innovations of Inventor Hungming Chang
Introduction
Hungming Chang is a notable inventor based in Cupertino, California. He holds a total of 10 patents, showcasing his significant contributions to the field of technology and innovation. His work primarily focuses on adaptive transmission systems and channel adaptation methods.
Latest Patents
One of his latest patents is for an adaptive transmission system in a network. This invention involves a network node that can adjust its transmission rate based on current network conditions. Initially, the node transmits data at a first rate, and if errors occur, it reduces the number of data bits in the current packet while increasing redundant data. This process continues until error-free transmission is achieved. Another significant patent is for methods and apparatus for channel adaptation in a discrete multi-tone (DMT) based system. This invention allows multiple nodes to communicate over residential wiring, such as telephone lines, without the need for complex equalizers. By differentially encoding data prior to transmission, the system overcomes amplitude and phase distortion, ensuring effective data recovery.
