Title: David O Anderton: Innovator in Digital Communication Technologies

Introduction

David O Anderton is a notable inventor based in Rancho Santa Margarita, CA (US). He has made significant contributions to the field of digital communication, holding a total of 7 patents. His work primarily focuses on enhancing the efficiency and quality of signal transmission in various communication systems.

Latest Patents

One of his latest patents is titled "Modulation switching for DSL signal transmission." This innovation involves a digital subscriber line (DSL) communication system that utilizes the high-frequency band of a standard telephone line without requiring a plain old telephone service (POTS) splitter in the resident's home. The system employs constant envelope modulation or quadrature amplitude modulation for outputting DSL signals upstream to a central office. When a telephone is detected as off-hook, the DSL modem uses constant envelope modulation to reduce intermodulation product distortion, which minimizes audible noise for the user. Conversely, when the telephone is on-hook, QAM is utilized to maximize the upstream data rate capability in the DSL frequency band.

Another significant patent is the "Method and apparatus for dynamically switching between speech coders of a mobile unit as a function of received signal quality." This power management system allows a mobile unit to detect the quality of signals received from the base station. Based on this quality, the mobile unit can switch from a primary speech coder to a secondary speech coder that consumes less battery power while maintaining compatibility with the primary coder.
