  • Method of correcting distortion in a power amplifier
    Publication number: 20040142667
    Abstract: The invention is a method of correcting distortion in a power amplifier in a transmitter. The method includes applying an input time varying modulated data signal to the power amplifier which outputs an amplified time varying modulated data signal which is an amplification of the input time varying modulated data signal; storing samples of the input time varying modulated data signal; storing samples of the output amplified time varying data signal; using the stored input and output time varying modulated samples to provide a processor implemented model with parameters representing a non-linear characteristic of the power amplifier without the use of any polynomials; and producing predistortion coefficients.
