  • Adaptive digital post distortion reduction
    Patent number: 8498369
    Abstract: A method for adaptive digital post distortion reduction is described. An analog radio frequency (RF) signal is received. The frequency of the analog RF signal is downconverted using analog circuitry. The analog RF signal is converted to a digital signal using an analog to digital converter (ADC). Digital post distortion reduction is applied to the digital signal to reduce nonlinearities in the digital signal.
