ABSTRACT:
Estimating non-linearity of a power amplifier includes receiving signals at a first location. The signals include an input signal, a pre-distorted signal, and an output signal. The output signal exhibits distortion, including a non-linearity effect, with respect to the input signal. The power amplifier is located at a second location remote from the first location. The non-linearity of the power amplifier is estimated in accordance with the signals at the first location using an inverse model. Pre-distortion information is calculated according to the estimated non-linearity using the inverse model. The pre-distortion information is sent to a pre-distorter at the second location, where the pre-distorter can reduce the non-linearity effect using the pre-distortion information.
