Abstract
For the weakness of the existing predistortion algorithm, when large amplitude component in the modulation signal which is more than the voltage in saturation will be limited, leading to predistortion algorithm become invalid, and a new joint RF power amplifier (PA) linearization method is proposed. The method in this paper combines Peak-to-average Power Ratio (PAPR) reduction method base on u-law with predistortion algorithm, first compressing the signal amplitude by using PAPR reduction method, then linearizing the modulation signal by using predistortion algorithm, two boxes supplemented to each other, solving the weakness of the existing predistortion algorithm. The simulation result shows that the proposed method can effectively improve the power spectrum of the signal with about 5 dB out-of-band distortion compensation, effectively improve the Bit-Error-Ratio (BER) performance of system, and reduce the gap to the original signal less than 2 dB when the BER performance is 10-5 in nonlinear AWGN channel.
