Patent ID: 8340602

Claim:
A method, comprising: transmitting a non-predistorted first transmission signal via a radio-frequency transmitter power amplifier of an amplifier system; receiving a first receive signal indicative of the non-predistorted first transmission signal via a radio-frequency receiver; assessing a first set of signal information comprising: determining a first input value indicative of an input characteristic comprising an amplitude/phase of the non-predistorted first transmission signal; and determining a first output value indicative of an output characteristic comprising an amplitude/phase of the first receive signal; determining the first output value falls within a range; binning the first set of signal information with a second set of signal information comprising a second input value indicative of an input characteristic of a second transmission signal and a second output value indicative of an output characteristic including an amplitude/phase of a second receive signal, wherein the second output value falls within the same range as the first output value; and generating a predistorted transmission signal, comprising: receiving an input signal to be transmitted; determining that the input signal is to be transmitted with an output characteristic that falls within the range; retrieving the first set of signal information and the second set of signal information; determining an input average value, comprising averaging at least the first input value and the second input value of the second set of signal information; determining an output average value, comprising averaging at least the first output value and the second output value; determining a final input value indicative of an amplitude/phase based on the input average value and the output average value; predistorting an incoming signal in accordance with the amplitude/phase indicated by the final input value; and generating the predistorted transmission signal from the predistorted incoming signal.
