  • Cross-correlation detection and elimination in a receiver
    Patent number: 7680178
    Abstract: A communication device with cross-correlation detection based upon statistical tests to determine whether the off-peak signal energy is consistent with auto-correlation energy levels.
    Type: Grant
    Filed: December 7, 2005
    Date of Patent: March 16, 2010
    Assignee: SIRF Technology, Inc.
    Inventors: Sundar Raman, Reza Abtahi, Steven A. Gronemeyer, Andrew Chou
  • Fast search GPS receiver
    Patent number: 7623067
    Abstract: A system within a multi-channel GPS receiver that searches for Global Positioning System (GPS) satellites by receipt of a plurality of GPS signals where each GPS signal corresponds to a GPS satellite having a GPS satellite identification number (ID) is shown. The system may include a controller in control of the multi-channel GPS receiver that assigns each GPS satellite ID that corresponds to each of the plurality of GPS signals received by the multi-channel GPS receiver to an individual channel of the multi-channel GPS receiver and a monitoring channel selected by the controller from the multi-channel GPS receiver that monitors the received GPS signal.
