Rex L. Baker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multiple antenna home base for digital cordless telephones
    Patent number: 5696798
    Abstract: The present invention provides methods for combining antenna diversity and gain control in a communications system using a single chain of receiver electronics. A number of input parameters related to various characteristics of a received signal are used to determine the quality of the received signal. The antenna diversity and gain control procedures are enabled or disabled based on the signal quality. The antenna diversity procedure estimates the signal level of the non-operational antenna using an infinite impulse response digital filter. The gain control procedure selects one of three gain paths based on the received signal strength.
    Type: Grant
    Filed: December 15, 1995
    Date of Patent: December 9, 1997
    Assignee: Rockwell Semiconductor Systems, Inc.
    Inventors: David Wright, James E. Petranovich, Rex L. Baker, Neal K. Riedel
