Error Analysis and Compensation Algorithm for Digital Predistortion Systems
Baseband Digital Predistortion based on the LUT is a popular method to improve the performance of high power amplifiers. The feedback loop is the key unit to obtain the sample signals based on which the model of the PA is built. The imperfectness of the modulator and demodulator will limit the improvement of the predistortion. In this paper, error items of the demodulator in the feedback path are analyzed and the compensating algorithm is derived.
