  • Wave packet communication subsystem for determining the sync pulses and correlating the data pulses of a wave packet
    Patent number: 4688251
    Abstract: A subsystem of a wave packet communication system uses the same sets of receivers and correlators to detect both the sync pulses and the messages carried by different wave packets. The system does this by taking the sync pulses from each packet and generating a corresponding preamble on the basis of a modular arithmetic algorithm based on prime numbers such that different messages from different transmitters can be received by the same subsystem simultaneously.

  • Capture protection for pulse signal tracking system
    Patent number: 4110756
    Abstract: This invention relates to a method of separating pulses of a particular signal source from the total signal environment. A tracking gate technique is used in which guard bands are provided on ether side of the tracking gate. The guard bands detect interfering pulses before they coincide with the pulses being tracked. Upon detection of an interfering pulse the tracking system is switched from a leading edge tracking mode to a lagging edge tracking mode or vice-versa to prevent tracking gate "capture".
