  • Demodulation of an optical signal under control of a kalman filter
    Patent number: 8213810
    Abstract: An optical receiver and a method of demodulating an optical signal. The method includes combining a received optical signal with a local oscillator signal to construct a complex signal indicative of an optical field of the modulated optical signal and processing the complex signal recursively under control of a Kalman filter that enforces a constraint. The receiver includes an optical hybrid that combines a received optical signal with a local oscillator signal, a detector that recovers components of a complex signal, a processor that receives these components, and instructions that cause the processor to process the components of the complex signal recursively under control of a Kalman filter that enforces a constraint to recover data.

  • Three dimensional RF search system
    Patent number: 8199053
    Abstract: An RF signal detection process by incorporating direction detection of the RF signal along with energy detection to arrive at a signal of interest (SOI). The SOI is identified by matching direction detections and energy detections. Low-level and noise-like signals can be reevaluated for unresolved direction detections or energy detections. The RF signal detections can be filtered based on valid direction detections very early on in the processing chain to reduce the amount down-stream processing required.
