  • Precorrection of a nonlinear amplifier
    Patent number: 6812792
    Abstract: A method and apparatus are disclosed for predistorting an input signal to a non-linear amplifier. An appropriate precorrection is determined for the input signal over a series of iterative stages according to an amplifier model. The amplifier model includes a limiting function that clips the input signal to reduce error due to amplifier saturation. The determined precorrection is then applied to the input signal.
    Type: Grant
    Filed: January 2, 2003
    Date of Patent: November 2, 2004
    Assignee: Harris Corporation
    Inventors: Anders S. Mattsson, Carlos Abascal, Wayne Duello, David Danielssons
