Abstract: |
In this paper, a novel Look Up Table (LUT) algorithm based on the digital pre-distortion (DPD) is proposed. This algorithm takes into account the linearity and the adaptive convergence rate. Then, the proposed pre-distortion LUT algorithm is simulated by using 16-QAM modulate signal under software MATLAB, and some comparisons with the secant method in terms of the constellation, the mean square error and the bit error rate (BER) are made. Finally, the pre-distortion system based on our proposed LUT method is verified with Agilent's software ADS, mainly aiming at the analysis of the signal spectrum.
