Abstract
Considering efficiency improvement of digital power amplifier in the current 3G base stations, the application of CFR algorithm module was proposed. The effect of the application of CFR algorithm module on performance of digital power amplifier was analyzed, and block diagram of system was showed. The whole process of improving efficiency of power amplifier by filtering error signal after clipped, and getting clipped signal by subtracting error signal from original signal was described in detail. Finally, the comparison between performance parameters of MATLAB simulation results before and after CFR algorithm application are given, which indicates PAR and CCDF decrease after CFR is applied, and the method is practically validated.关键词
