METHOD AND SYSTEM OF ADAPTIVE PREDISTORTION OF A WIRELESS TRANSMITTER |
摘要 |
<p>A method of adaptive predistortion of a power amplifier, characterised in that the method comprises the steps of: storing values of a plurality of corresponding first and second coefficients; selecting one of the stored first coefficients; processing a first signal with the first coefficient to produce an input signal for the power amplifier; - amplifying the input signal in the power amplifier to produce an output signal; calculating an error value from the output signal and a previously selected first coefficient; selecting a stored second coefficient corresponding with the previously selected first coefficient; updating the previously selected first coefficient with a value calculated from the error value and the second coefficient; updating the second coefficient; and replacing the previously selected first coefficient and corresponding second coefficient with the updated first and second coefficients respectively.</p> |
