Patents by Inventor Ronald Bruce Harding

Ronald Bruce Harding 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).

  • Patent number: 7912463
    Abstract: The application relates to wireless networks and more particularly to a method of reducing factory test time of receiver sensitivity in a Code Division Multiple Access (CDMA) wireless device. Under TIA/EIA/-98E, the radio frequency (RF) sensitivity of a CDMA wireless receiver is the minimum received power, measured at the mobile station antenna connector, at which the frame error rate (FER) does not exceed 0.5% with 95% confidence. In order to reduce the test time of FER test method, the relation between correlated energy (or Ec/Io) and FER is determined using simulated traffic and the correlated energy (or Ec/Io) measurement is then used as the test parameter on like models to achieve the same or superior test confidence with significantly reduced test time.
