  • Method and apparatus for improving digital predistortion correction with amplifier device biasing
    Patent number: 8374282
    Abstract: A method, apparatus, and electronic device for using digital predistortion are disclosed. A transmitter 212 may transmits a transmission signal. A receiver 214 may monitor the transmission signal to execute digital predistortion of the transmission signal to compensate for distortion. A field programmable gate array or application specific integrated circuit 226 may adjust a power amplifier bias to improve the digital predistortion.
    Type: Grant
