  • Weighted memory polynomial method and system for power amplifiers predistortion
    Patent number: 9660593
    Abstract: A system and method for linearizing a power amplifier using digital predistortion technique is provided including processing circuitry, the processing circuitry configured to apply a digital predistortion function based on a weighted static polynomial function, a weighted dynamic polynomial function and a threshold parameter which splits the nonlinear transfer characteristics of the device under test into a region where the static nonlinearity predominates and a region where the dynamic distortions predominate.
    Type: Grant
    Filed: September 30, 2016
    Date of Patent: May 23, 2017
    Assignee: King Fahd University of Petroleum and Minerals
    Inventors: Abdalla Ebrahim Abdelrahman, Oualid Hammi, Azzedine Zerguine
