  • Method and circuit configuration for resynchronizing a clock signal
    Patent number: 6721377
    Abstract: A method for resynchronizing a clock signal, includes the steps of defining a presettable clock signal, dividing a first clock signal having a first frequency with a programmable digital frequency divider to produce a second clock signal having a second frequency, measuring the second clock signal with a digital control circuit, and programming a programmable digital frequency divider with the digital control circuit, such that the second clock signal corresponds to the presettable clock signal.

  • Interference cancellation in a spread spectrum communication system
    Patent number: 6278726
    Abstract: A transmitter transmits a spread spectrum pilot and data signal. Each signal has an associated chip code. A receiver receives the transmitted pilot and data signal. The received pilot signal is filtered using the pilot chip code and weights are determined for components of the received pilot signal using an adaptive algorithm. The received data signal is weighted by the determined weights and filtered with the data signal chip code to recover data from the received data signal.
