Amy Gayle Hundhausen 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: 8798125
    Abstract: The present invention includes a method of determining a phase estimate for an input signal having pilot symbols. The method includes receiving a plurality of pilot symbols, and then multiplying two or more pilot symbol slots by corresponding correlator coefficients to correct a phase estimate of the input signal.
    Type: Grant

  • Patent number: 8761328
    Abstract: An update algorithm for equalizer coefficients in a communications system using phase correction symbols. Instead of using a traditional all symbols slicer update algorithm, the equalizer is updated during phase correction symbols for optimal performance in low signal-to-noise ratio conditions. In lower signal-to-noise ratio conditions, the equalizer uses a phase correction circuit to compensate for distortion caused by a communication channel when a demodulated data stream contains an unknown phase offsets resulting from a fast dynamic distortion. More specifically, the phase correction circuit uses a phase correction signal to correct for the unknown phase offsets in a demodulated data stream in lower signal-to-noise ratio conditions. The equalizer then corrects for distortion caused by the communication channel based upon the phase corrected demodulated data stream.

  • Patent number: 7769111
    Abstract: A method and apparatus for the detection and correction of large carrier offsets. A set of known correction carrier offsets are used to translate an input signal having a carrier offset. After applying each correction carrier offset, a state of a timing recovery loop is evaluated. The set of known correction carrier offsets are sequentially used to translate the input signal until the timing recovery loop is locked. The carrier offset is substantially acquired when the timing recovery loop is locked.
