ADAPTIVE PREDISTORTER BASED ON THE PROBABILITY DISTRIBUTION FUNCTION OF THE OUTPUT AMPLITUDE |
摘要 |
<p>This invention is about a novel estimation technique for generating a predistortion function to compensate for the AM-AM and AM-PM non-linear conversion distortions of non-linear power amplifiers or non-linear circuits . Based on the cumulative type of power amplifier output envelope, a non- parametric baseband predistortion function is derived. The non-parametric approach avoids any model mismatch. In addition, the technique does not need to demodulate the input signal. Furthermore, it minimizes the effect of the power amplifier non-linearity and significantly improves the system performa nce</p> |
