  • Acquisition and tracking of burst code signals
    Patent number: 7822157
    Abstract: A digital communication system includes a generator for generating a plurality of pulse trains, each having a different timing, and pre-compensation circuitry for synchronizing the plurality of pulse trains to a timing signal. The system also includes comparison circuitry for simultaneously comparing a received burst code signal to each of the plurality of pulse trains, where the burst code signal is synchronized to the timing signal, and a detector for detecting which of the pulse trains is a closest temporal match to the burst code signal. The pre-compensation circuitry operates to reduce acquisition time and keep PN code uncertainties within the range of the comparison circuitry.

  • APPARATUS FOR RAPID PN CODE ACQUISITION
    Publication number: 20070014336
    Abstract: An apparatus and method of determining a signal code. The method comprising steps of acquiring and correlating a signal with a first code sequence. In response to the timing lock is achieved. Also in response to the signal correlation, an acknowledge from a receiver of the signal to a transmitter change to a second code sequence.
