  • Power conscious self-healing transceiver systems and methods
    Patent number: 8983390
    Abstract: The various embodiments of the present disclosure relate generally to power-conscious self-healing transceiver systems and methods. An embodiment of the present invention provides a method of power-consciously self-healing a transceiver system. The method comprises providing a transceiver device having a plurality of tuning elements configured to control a plurality of specifications of the device, determining initial values for the plurality of tuning elements, and performing a hardware-iterative gradient search to obtain values for each tuning element such that the plurality of specifications are within a tolerated range.
    Type: Grant

  • Systems and methods for distortion measurement using distortion-to-amplitude transformations
    Patent number: 8358169
    Abstract: The presently invention is directed to ways to measure distortion effects while allowing for the possibility of significant reduction in test cost. An exemplary embodiment of the present invention provides a method for amplifier distortion measurement including comparing a first amplitude response of an output signal from a power amplifier to a second amplitude response of a reference input signal to determine a set of Amplitude-to-Amplitude (“AM-AM”) distortion values. Additionally, the method for amplifier distortion measurement includes equalizing the first amplitude response of the output signal to match the second amplitude response of the reference input signal based on the set of AM-AM distortion values and creating a difference signal based on a comparison of the equalized output signal to the reference input signal.
